I think that particular video of the tablet is actually very nice. Since they're showing the video already, the "alpha" part pretty much probably means that the UI is ready, so I don't expect it to change much from that.

So yeah, if the marketting is done right (which, in reality, will decide the fate of these devices, not Qt or any other acronym), I don't see why people wouldn't want devices like that. I certainly think it looks pretty cool, even compared to any other OS I can think of. It really isn't "spectacular" in any way, but it doesn't fail in any way either. It doesn't appear to have the Symbian ugliness or the Maemo inconsistent clunkiness to it, so yeah, I think it might work on a tablet for the mass market too IF it came with the same sort of services you can get for the Ipad and the armada of Android tablets soon coming, meaning magazine subscriptions, ebooks, video services, etc, whatever people will want. Of course, I'm also supposing that the Meego devices will be clearly cheaper than the Ipads and that there's a lot of choices between them, not just one or two Nokia tablets available, vs. Apples one device (works for them) and Android's 40.

I think the main point for why it just might succeed on tablets is that it's not yet late to the game, really: the Ipad is here, but the competition (Android tablets) is not. The whole "what are these types of computers used for" idea is still in the process of forming, it's not very established yet. So if the Androids don't come out (too much) before the Meego tablets/pads/whatever, and they seem to match up pretty evenly in terms of "what you can do with it" (forget 10% speed differences or Qt, tools don't matter, success does), I don't see why these Meegos couldn't, if properly marketted, compete.

For phones, I frankly don't believe in Meego one bit. When you strip that video there into "how it must look on a phone", it'll be pretty much Android minus the 100,000 apps, Google-hookup and marketting. If we think about what Nokia does with phones, there's going to be some god-awful Nokia email program, calendar that supports nothing, and horrible Ovi services slapped to that, so yeah, fail.

My guess: a minor phone OS but one of the major tablet OS's.
