Short versionWasted money. Don't do it.
Too light, too small
Literally. An attempt to operate it will most probably move it. It is shallow (7 1/16", or 180mm), nothing will stand on top of it to hold it down (except a decent paperweight, maybe).
SlowNo, not just slow. Infuriatingly slow. Glacial. A computer you buy for the same money will work faster.
ClumsyNavigation is awkward (did I mention it is glacial?) and inconsistent. There are at least two different virtual keyboards, one of them is ABCDEF, the other is QWERTY.
Good luck trying to access a network service when there's a firmware update (hint: you can't). Normally, it takes two tries (it hangs at 0% download until power reset) and no less than 5 minutes.
VindictiveGood luck trying to de-authorize accounts. Amazon says it takes 36 hours to do so, still waiting for expiration (UPDATE: There's "Unlink from Amazon" entry in Amazon Help menu). Netflix? Even better, an explicit "disconnect all" command on Netflix site disconnects, well, all devices - except this one. And the documentation is a jewel - here, take a look:
Oh, and they forgot to tell you that you need to activate this sequence from Netflix home screen.
BottomlineThe idea was to save some money and get rid of HTPC. All in all, if you can get very decent Netflix experience on a cheap Android device, I thought, this should work just fine.
Well, it doesn't.
You get up to what you paid for. I'm afraid that all devices in this price range will behave in a similar way.
