As I said before, I also have the V7's predecessor, the SmartQ 7. I took the opportunity to set the 2 devices next to each other and do a direct comparison. The tablets run the same version of Ubuntu, and SmartQ took the time to customize the firmware so it works better on a small touch screen. Even though the V7 has more RAM and Flash, I could not see a difference in performance. I have to wonder why Smart Devices released the v7. I do not see that they made any significant improvement.
Android & WinCE
Quite simply, I found them to be useless because neither OS had Wifi support. Given that the V7 is a Mobile Internet Device, I would say that Wifi support is a pass/fail issue. Until SmartQ fixes this, there is no point in trying to use these OSes, and that eliminates one reason to pick the V7 over its predecessor.
The broken Wifi support is especially critical for the Android firmware. One of the key design decisions for Android is downloading new apps over the air from the Marketplace, Appslib, etc. The V7 is cut off from these sources. Not being able to use Appslib is particularly damaging; most of the apps on Appslib are designed for the V7 screen resolution.
I'd recommend almost any other tablet over the V7. I'm going to put mine back in its box and put it on a shelf in my closet. I got it so I could test Android reading apps, and I plan to keep it around for that purpose. But as soon as I find a better alternative, the V7 will be sold (or given away).
