I cry foul!
A quick scan of the archos 101 review reveals that one of the reviewers biggest gripes - lack of market support - is also an issue with the archos tablet, yet the reviewer skims over it as it is easily installable via a third party website. So, the outdated single core archos with only 256MB ram gets a higher score than the vega.
Secondly, this thing is unbrickable, so not matter if you put custom firmwares on there, or even linux distros such as ubuntu, you can ALWAYS get back to stock if you need to send it back. So you don't have to worry about the warranty. Not that I expect it would be an issue anyway as DSG are well aware of the vega community as modaco and are actively encouraging it, as it helps them to sell more devices without breaking googles android apps licensing restrictions.
Thirdly, the actual hardware is made by shuttle, and as such there are are various companies rebadging this thing, several of whom have promised Honeycomb within the next few months. And given the Tegra 2 chipset, the vega is just as capable of running Honeycomb as the Motorola Xoom, but at half the price.
I had a vega myself for a while but one of the speakers failed and after getting it refunded I decided to wait and see what the xoom would be like. Overpriced is the answer, so I will be picking up a new vega as soon as I have the funds again.
