Going out on a limb here, but I love the HP TouchPads (I have 3 of 'em). Sadly, it is a discontinued device but can still be found new for about $250 or pre-owned for less on eBay.
Best thing about it is, it can dual-boot two operating systems...its native webOS, or Android. Plus on the webOS side of the device, you can load a very robust stable of homebrew apps, patches and tweaks. So although there are very few new apps coming through HP's App Catalog, you have homebrew apps on the webos side, and Android on that side of the device.
Full disclosure: I volunteer as an "Expert" on HP's support forums, primarily for webOS and Palm (yeah, remember them?) devices, and soon for HP's upcoming Slate 7 Android tablet which is expected out very soon.
