Deskbound Chrome

Acer Chromebox CXI Top Angle ViewForget about the Chrome platform only being available in notebooks because Acer’s Chromebox CXI family plants it firmly on a desk, library kiosk or common room. Powered by an Intel Celeron processor, the CXI comes with 2- or 4GB of RAM and 16GB of storage space. Still the system is tiny, can be attached to the back of a monitor and has a Trusted Platform Module (TPM) built in. It comes with DVI and HDMI monitor ports as well as four USB 3.0 connectors. It should be available before school starts in most places for between $180 and $220 with a keyboard and mouse included.  

 

 

Power on the Desk

C560 aAnyone who tells you that the desktop is as dead as the dinosaur is either misguided or lying to you. Inexpensive desktop PCs are everywhere and often make a compelling case where performance counts for more than portability.

Take, Lenovo’s C560 Touch, an all-in-one system that is not only a good value but can put desktops and notebooks to shame. At 17.8- by 22.6- by 6.1-inches, it is a bit large, particularly for a system with a 23-inch screen. That’s because there’s an extra 0.7-inch rim around the display as well as a half-inch screen frame.

The mid-range configuration that I looked should provide all the power any school task requires with a Core i3 4130T processor that runs at 2.9GHz. It, however, lacks Intel’s TurboBoost variable speed technology and vPro security enhancements. On the other hand, the C560 is top shelf with a generous 8GB of RAM, a 1TB high-performance hard drive and up to 5GB of online capacity with Lenovo’s Cloud Storage service.

One of the best equipped systems around, it includes a 720p Web cam and a DVD drive that can create discs as well as play them. The system has Dolby Advanced Audio, a set of built-in speakers and Lenovo sells a matching pair of external speakers for $30. 

The configuration that I looked at is sold at Best Buy for $765. It’s not only a good value, but Lenovo also sells a stripped down model for $700 with 4GB of RAM and a similar non-touch version for $615. The company also has a higher performance model for $829 that uses a Core i5 processor and includes a 2TB hard drive.

C560 bThe C560 Touch comes ready to teach with a matching keyboard and mouse. It takes just a few minutes to set up. All you need to do is screw on its dull silver base. The stand’s legs look more like sculpture than something purely functional. On the downside, the system doesn’t have VESA mounting holes for wall-mounting the unit, so it will be deskbound.

The center of attention is the system’s 23-inch HD display. It shows 1,920 by 1,080 resolution, uses Intel’s HD 4400 graphics engine and has 32MB of dedicated memory. It can use up to 1.76GB from the system RAM for a total of nearly 1.8GB of video memory. It, however, lacks a Windows key under the screen, although the included keyboard has one.

Rather than a capacitive multi-touch display, the C560 Touch has an infrared system that can interpret up to five independent touch inputs. The screen is recessed, which can make some touch moves awkward, but it works reliably, regardless of whether it is touched with a finger or a generic stylus. Unfortunately, the screen wobbles a little when it is tapped.

The display can’t be raised or lowered to accommodate different size users, but it can be tilted from 85- to 115-degrees to get to a comfortable angle. It isn’t able, however, to get to a full horizontal orientation for small kids to finger paint on the screen, though.

Below the screen on the left are LEDs that show the computer’s activity and whether the WiFi radio is turned on. The right side has adjustments for volume and screen brightness. It was able to deliver 203 candelas per square meter of brightness, which is a little dull for a desktop system but is on a par with a good notebook. On the downside, its color balance is slightly off with greenish yellows, but for most teaching situations, like interactive Web sites and online curriculum, it should be fine.

C560 cThis is the system to get if you need a good assortment of ports, such as in a computer lab or science room. While it lacks a good old VGA connector, the system has an HDMI plug for using a projector or external monitor. There’s also a pair of USB 3.0, four USB 2.0, microphone and headphone jacks; it has a wired LAN port as well as a full-size SD card slot.

The C560 Touch goes against the grain for all-in-one systems because it can be opened, cleaned and upgraded. All you need to do is slide the lower half of the back panel off to expose the system’s memory chips, hard drive and DVD drive.

The system is very powerful, particularly compared to what it is likely replacing. It scored a 1,820.4 on Passmark’s PerformanceTest 8 suite of tests that checks out all the system’s major components, and the system should be able to keep up with just about any school activity. Even when it is running full blast, the system only uses 36-watts of electricity, less than one-quarter what the typical four-year old desktop consumes.

It all adds up to annual operating expenses of less than $9 if it’s used for 8 hours every school day and is in sleep mode for the rest; I used the national average of 12 cents per kilowatt hour of electricity.

In addition to Windows 8.1, the C560 comes with a slew of software aimed at children and education. In the final analysis, the C560 is one of the best values around that combines low operating expenses and the ability to get inside with high-performance. In other words, it can change your mind about desktop computing.

Mac All-in-One Bargain

HeroAt $1,099 the latest Apple iMac represents a price drop of $200 from the previous budget model. The 21.5-inch screen can show full HD resolution and comes with Intel’s HD Graphics 5000; the 27-inch iMac still costs $1,800.  It has a dual-core Core i5 processor that can run as fast as 2.7GHz, 8GB of RAM and a 500GB hard drive. It may be more expensive than comparable PC all-in-one computers and not include a touch-screen, but it a good way for Mac-centric schools to fill up a classroom or computer lab with computers.

 

 

ISTE UPDATE: Macs on the Cheap

Mac to schoolGot a school full of Macs, but not enough money to replace the old and broken ones? Mac to School refurbishes Macintosh computers for schools and makes sure they’re ready to handle the Common Core assessments that will be part of most educational plans. To make sure that they are ready for this level of instruction, Mac to School’s refurbished computers now meet the requirements set down for CC assessments. All desktop systems have at least 1GB of RAM and can work with Apple’s OSX 10.4 operating system while MacBooks come with at least 2GB of RAM and OSX 10.7 or higher.

Android Conquers the Desk

22 - A2272PW4T hi-res (1)With HP’s Slate 21 Pro, it’s clear that Android computers aren’t just for phones and tablets anymore. In fact, with a bigger screen, keyboard and mouse, the software really shines on the desk, whether it’s for general Web work and research or use in specific classroom situations.

A case in point is AOC’s A2272PW4T, an inexpensive all-in-one computer that rather than Windows or Macintosh software relies on Android 4.2 software. This is truly a different sort of classroom computer, which I realized as soon as I opened the box. Printed on the inside flap was not only helpful instructions on how to remove and set up the device, but a connection diagram and a run down on how to tilt the screen. It’s a big step forward that can help get the system out of the box and set up quicker. I hope that others imitate it.

Like the Slate 21 Pro, the A2272 system is big. It occupies 23.5 by 3.4-inches of desktop space and is 15-inches tall. It should just about fit on a standard student desk, but can be used in a computer lab, on a library table or at a public kiosk. The system has standard VESA mounting holes on the back so it can be used with a bracket or set on a wall.

To do this would miss out on one of the A2272’s best qualities. It has an easel leg that allows the screen to be adjusted to between 15- and 60-degrees, but – as is the case with the Slate 21 Pro – neither full vertical nor horizontal orientation. It is stable and secure and doesn’t wobble when tapped.

22 - A2272PW4T hi-res (2)And, expect that the system will be tapped and touched a lot. Its 21.5-inch screen can show 1,920 by 1,080 full HD resolution and is touch sensitive. On the downside, the display is deeply recessed and it can respond to only two inputs at a time. This makes it better for individual work than for group collaboration.

While the A2272 has physical buttons for turning it on and off, optimizing the picture, adjusting the volume and switching between using the system as an Android computer and a monitor, it lacks dedicated buttons for Android’s main functions. These are set up on the bottom of the screen in the left corner and take a little time to get used to. The system offers something others don’t: a screenshot button for turning what’s on-screen into an image file.

Inside is an Nvidia Tegra T33 quad-core processor that can run at 1.6GHz, which is slightly slower than the Slate 21 Pro’s similar 1.8GHz CPU. Both come with 2GB of RAM, but the Slate 21 Pro is equipped with 16GB of solid state storage, while the A2272 includes half as much.

The AOC all-in-one takes the lead in terms of what you can connect to. In addition to four USB ports (one of which is a micro-USB), the system has HDMI, audio and a VGA connector for use with an older monitor or projector. As is the case with the Slate 21 Pro, the AOC system can’t send a signal to a projector or larger display for the whole class to see.

If you use the included USB cable to link the A2272 with a computer, it can be used as a touch-screen monitor. The display responds quickly and reliably to taps and swipes, but can only handle two inputs at a time. In addition to a 720P Web cam, the system has a pair of 2 watt speakers that can get loud enough for the whole room to hear.

22 - A2272PW4T hi-res (3)In terms of performance, the A2272 was a step behind the Slate 21 Pro with an Antutu Performance score of 16,674, making it roughly half as powerful. Still, it was able to work well with everything from the University of Colorado’s PHET science and math simulations to handling  an assortment of Google Docs and a variety of online curriculum items. While being used, it consumes 27 watts of power, slightly more than the Slate 21 Pro does, but less than most light bulbs. All told, it should cost less than $7 a year to operate the system.

Like the Slate 21 Pro, the A2272 comes with a three-year warranty, but it lacks HP’s thoughtful Classroom Manager client software. On the downside, while the Slate 21 Pro has a nice cable cover, plugs directly into a wall outlet and comes with a basic keyboard and mouse, the A2272 doesn’t. The system’s AC adapter is an inconvenience, figure that a keyboard and mouse will add about $20 to the price tag, putting the $379 Slate 21 Pro and $360 A2272 on an even playing field.

For those schools interested in having touch in every classroom, the A2272 is an inexpensive and versatile way to achieve this goal.
