I think it's a waste of potential too. When I connected the iPad to an Apple Wireless Keyboard, I realized that it could be a really great computer, IF it had mouse support and support for multi-tasking. But it doesn't.
Yeah, and what's ironic is a lot of the productivity apps (IE Pages) use the same UI as desktop counterparts and would actually benefit from mouse/trackpad replacements.
However, the iPad is less than 3 years old, and its "ecosystem" (people seem to really like to use this word lately, so perhaps should I) is still under development. The apps available today are much more complicated and feature-rich than they were 2 years ago. Although the iPad is still very limited, it has evolved a lot.
I think we're already seeing the limits on iOS software and I don't expect it to evolve much further. iOS software is pretty much a race to the bottom and there's only so much devs can do with a cheap pricepoint in a commoditized store. I like everything about iOS and Apple mobile devices except their software library, which to me is the type of software you would've found in cardboard sleeves in the $5 bargain bin at Fry's 10 years ago.
Google is certainly not capping the development of Android as much as Apple is doing with iOS. And Microsoft made a very capable Windows RT (even though there are quite few apps developed for it yet). If competition poses a threat to Apple, then it may find itself forced to loosen the limitations of iOS.
Google is in the same boat as Apple because they follow the same business model. Notice how both Google and Apple don't really care about the pricepoint of software that much. Google gives away their software for free because it's a gateway to ads. Apple makes their software cheap because it's a gateway to hardware. Both of them use commoditized distribution to make their app stores ultracompetitive among developers. Third party developers are affected by this because they have to pricedrop accordingly. Software quality follows
