I have a laptop and a smartphone, so I don't really see a need for a tablet personally, but if I were getting one, I'd probably get the iPad 2. I had high hopes for Honeycomb and I hope Google polishes it up soon. That and I hope we see more apps for it. I may be up for a tablet in the future. I primarily use my laptop around the house. When I do travel, I mostly use it for checking email and such. So I could see myself going back to a more powerful desktop and getting a tablet for portability. I'll probably wind up ditching the smartphone mostly because I don't use it enough to justify the cost of the service plan.
Other than not allowing duplication of built-in apps, I don't see Apple's terms as being overly unreasonable. Most apps are rejected because they're unstable. If you want to look at dirty movies, the provider can build a capable web app. Actually, that's one thing about the App Store I don't care for - instead of building good web apps, we get lots of specialized apps when they're not really needed.
In any case, the market is still new. I suppose it would be cool if HP could graft the webOS UI on top of Android so there wouldn't be yet another OS out there. I wanted to like the Pre because I really liked webOS, but the hardware let it down. Consequently, there's few apps for it. But to each their own. I honestly don't see why people hate Apple so much. If they were the only alternative perhaps, but they aren't. Though one could argue that for tablets, they're currently the only viable one - until Honeycomb and Android Market catch up, which should hopefully happen soon).
