Concerned about the 7" form factor. I thought Steve Jobs was being disingenuous when he bashed the 7" form factor. An iPad is basically a bigger iPod touch... Which many have stated as a negative but the only problem with the iPod touch was the mistake apple made in calling it an iPod and it's small screen size. The iPod touch is a hell of a tablet computer and the extra screen real-estate on the iPad makes it many many times better.
Have not used a playbook so won't knock it but it's future or lack thereof will all be about the apps... The only negative I have discovered which may affect playbook and android users is that non native iPad apps meaning those made for the iPod suck badly. I have deleted most of them in favor of native iPad apps. Another issue is that with all the iPad native apps available the selection of iPad apps as opposed to iPod apps is severely lacking. I can't even imagine the poor selection of native Android 3.0 and playbook apps. Those who question the importance of quality native apps must not have used many of these apps to see how important apps truly are.
