I got a free playbook when I bought a new car as a gift from the dealership. I do find the interface excellent for multitasking and web browsing, the screen is great for video and the speakers are even reasonably good. I find it very frustrating that it has no native email app because I don't own a blackberry phone, but supposedly that will be resolved shortly. It has a nice citrix app, there's a great 3rd party ebook reader for $1 on their market, and the need for speed and tetris games that come with it really show off its gaming capabilities effectively.
The ebook reader app that came with it limits you to only read books purchased from its own bookstore, so it's very limiting but at least effective. The PC interface/synch/backup software is pretty straightforward and works well, though it does not convert video files for me when transferring video like Samsung Kies software does, so I have to use handbrake first.
One big thing it's missing is Skype, though there is an app in the market called ReelPortal for video chat that it claims also exists on both the android and the apple devices, though I have not had a chance to confirm that or try it. wifi video chat would be pretty cool, too bad the upcoming (very limited) compatibility with android apps will not work with android video chat apps.
I DO hope someone comes up with a way to load android on this device (while still allowing the cameras to work), I would do it in a second. My wife has a Samsung Galaxy phone, and android has so many more apps.
