I recently got a 16GB WiFi Flyer and am happy with it. Its the first well-known brand tablet I have bought (Ainol and Teclast are well known in China but not ROW) and I can say I am pleased with it, considering its limitations.
Firstly, its single core. OK, not a big deal as I don't multi-task much on it as its for casual gaming, skype and a bit of net access.
Secondly, its really locked down tight. No rooting works easily, and once upgraded to Honeycomb, presently no root available at all.
Finally, Flash was only the Flash Lite 10.1 version and wouldn't upgrade in 2.3. HC fixed this and its now 11.1.
The Honeycomb OTA upgrade went without any issues. The tablet came with 2.3.3, and needed 2 subsequent OTA patches (2.3.4 and 2.3.4 patches) before 3.2.1 became visible. HC 3.2.1 is nice, quite different from 2.3 Gingerbread, but still smooth and responsive. One thing to mention is that the backlit buttons are disabled after upgrading to HC as they are onscreen buttons in 3.2.1.
The table it well made, screen is good, response is fine. A bit heavy, but it has a unibody design which must add weight - not really a bad thing as it feels solid and not likely to flex or break. I like the replaceable microsd slot cover design because if you scratch the lens of the back camera, you can replace it easily (new slot cover). Its speakers (dual on the back) are loud and quite crisp for a tablet, so multimedia is good. 720p plays fine using the supplied player, and you can always replace that with MX Player etc. if you prefer. VPN works - most china tablets I have tried don't work OOB. BBC iPlayer works great, and so do all flash webpages.
Watch out for good deals on this tablet as HTC are discontinuing them. If its under 200GBP, its worth it. At its old RRP, its more expensive than an iPad, so guess what people would buy....
