ViewSonic ViewPad 10pro

 If you’re interested in trying out the latest Android tablet software but have too much invested in Windows programs to walk away, ViewSonic’s ViewPad 10Pro could be a solution. It acts as a convenient bridge between these two worlds.

Over the course of a week, I worked and played with the ViewPad 10pro, which runs Windows 7 natively and also includes the BlueStacks Android emulation software that lets it run Android 2.3 (Gingerbread). The 1.8-lb. tablet is larger and about half a pound heavier than the iPad 2 and is available starting at $500 for Wi-Fi only — currently, there is no built-in 3G available.

(I’d previously looked at its predecessor, the ViewPad 10. The ViewPad 10 is based on Intel’s Atom N455 processor (rather than the newer Z670) and can be booted separately as either Windows 7 or Android 2.2, rather than running Android apps in emulation software as the ViewPad 10pro does.)

Two OSes in one

The ViewPad 10pro’s main selling point is its dual operating systems, and if you want access to both Windows 7 and Android, it’s a major plus. I was able to switch between Windows and Android at the flip of a finger without rebooting the system — just by tapping an icon. For example, if I were working in Windows, I could tap on the BlueStacks icon and in 2.2 seconds the Android home page came up.

I found it intensely liberating to pick and choose which application and environment was most appropriate for the job at hand. For example, I was able to work with Word, Excel and PowerPoint files using Microsoft Works (the system comes with neither Works nor Office included, but I loaded the former myself). This was interspersed with moving to Android to arrange my calendar, finger paint with Paint Joy, read with the Kindle ebook app and look over dozens of newspapers with Langtoland’s US Newspapers app. I also updated a website (in both Windows and Android) using the TypePad online blogging software.

The system comes with basic Android apps for Web browsing, email, scheduling and audio; there is access to the Android Market. It also includes DataViz’s Documents To Go Android app for viewing a variety of files as well as Thinix’s streamlined TabletBrowserand ViewSonic’s ViewDraw for doodling or annotating.

Hefty and equipped

The ViewPad can be a lot of tablet to carry around. At 0.6 x 10.4 x 6.7 in. and 1.8 lb., it is larger and heavier (by 0.5 lb.) than Apple’s iPad 2 tablet.

While the roughened surface on the back of the slate makes it easy to grip, the ViewPad 10pro’s rounded back means that it wobbles when it’s used flat on a table. Unlike the Archos 101 tablet, there’s no pull-out kick stand.

Its 10.1-in. display is slightly bigger than the iPad 2’s 9.7-in. screen. It has a 1.3-megapixel front-facing webcam, but lacks a rear-facing camera.

The display reacted quickly to both my finger motions (swipes as well as multi-finger) and a Wacom Bamboo stylus that I tried. The ViewSonic comes with Microsoft’s standard on-screen keyboard as well as Swype’s text-input system, which lets you slide your finger between characters to speed up typing.

Around its edge there are plenty of ports. On top of connectors for USB, HDMI and an audio headset, the system has a microSD card reader.

As opposed to Apple’s minimalist approach to controls, the ViewPad 10pro has several buttons. Besides the power and volume controls, there’s a Hold key that blanks the screen and will bring up the Windows Task Manager if held for five seconds.

To the side of the screen are the usual Android buttons for search, going back, accessing the Home page and accessing Android’s menu. This last button also brings up ViewSonic’s excellent Control Center when you’re in Windows. The Control Center has six icons for accessing system info, battery info, thermal condition, display, environment and device controller.

Test results

Over the course of a week of intensive use, I used the ViewPad 10pro with a drawer full of peripherals. I found it to be a reliable tablet — however, it won’t set any speed records. While I normally had no problems with performance, there were times when it lagged for a few seconds.

It scored a sluggish 143.0 on PassMark’s PerformanceTest 7.0 suite of benchmark tests, well off the pace set by another Windows 7 tablet, the Fujitsu Stylistic Q550, which scored 196.9.

With its 5,000 mAh battery, the ViewPad 10pro was able to run for 4 hours and 26 minutes hours playing back high-definition videos non-stop from YouTube via a Wi-Fi connection. That’s about half an hour longer than I got from the iPad 2 but short of the 4 hours and 59 minutes that the Fujitsu tablet achieved.


At $700, including Windows 7 Professional and 32GB of flash storage, the ViewPad 10pro that I looked at is expensive compared to a similarly equipped Samsung Galaxy Tab or iPad 2. ViewSonic also sells a $600 model with Windows 7 Home Premium and 16GB of flash storage as well as a custom configuration with Windows 7 Professional and 64GB of storage that costs $750.

It may not be the fastest, lightest or cheapest tablet around, but the ViewPad 10pro is an excellent tablet for professionals who need access to Windows applications while enjoying the app selection that comes with Android.

How we tested

To see how the ViewSonic ViewPad 10pro stacks up with other tablets, I used it for several hours a day over the course of a week to write emails, browse the Web, create and give presentations and watch online videos. After measuring, weighing and examining every major aspect of the ViewPad 10pro, I connected it to my office LAN, a public Wi-Fi network and a mobile hotspot.

Next, I used each tablet’s screen with both a finger (or two) and a Wacom Bamboo stylus. I typed with its on-screen keyboard, manipulated icons, drew figures and used multi-touch gestures.

After timing how long it takes to go from Windows to Android environments, I started up word processing and spreadsheet documents in Windows and incorporated them into a presentation. While I did this I occasionally went into Android to check my email, change a calendar entry and update a website using TypePad’s interface.

Next, I tried a variety of peripherals to make sure the ViewPad 10pro fits into the way businesses work, including the Adesso SlimTouch Bluetooth keyboard, SanDisk’s Cruzer USB drive, a Western Digital My Passport Essential external hard drive, NEC’s NP-V300X projector and OKI’s MC561 Color MFP wireless laser printer.

I measured the tablet’s overall performance with Passmark’s PerformanceTest 7.0 benchmark. The software exercises every major component of the system, including processor, hard drive, 2-D and 3-D graphics and memory and compiles the results into a single score that represents its performance potential. I ran the software 3 times and averaged the results.

With the system connected to YouTube, I played a series of 50 videos non-stop while Passmark’s BatteryMon charted the battery’s capacity and recorded the time it ran out of power and shut down.

Finally I set each system up with Passmark’s BurnInTest, which runs portions of the Performance benchmark in separate windows over and over again continuously, trying to find operational flaws. It ran for two days without an error.
