Also a PlayBook Lover...err.... Liker!
Have a 64GB PlayBook that was supplied by my employer (love the "out of pocket": price of $0!).
I was not sure what to expect, but being a BlackBerry phone user, it simply WORKED. The BB Bridge to tether the two just worked instantly, and Email, Calendar, etc... as well as mobile browsing all worked instantly... and that is all with the "old" operating system.
I have a couple of complaints, mostly the limited apps, but once I got over that hump I have realized that the device kicks the butt of other (even larger) tablets for business use. The lack of simple connectivity to an overhead projector is a show stopper for many(most) tablets out there, and is something that ism so easy on a Playbook.... step 1 connect HDMI cable from projector (or TV) to playbook... step 2 Enjoy.
Looking forward to the next OS simply for the additional Apps that developers have not been willing to port to the PlayBook.... not RIMs fault, per se, but still it is something they wear daily in the negative marketing.
The device and the true multi-tasking OS and interface is so nice compared to Android and iOS, I think that the bad press is simply based on the market share issue and the love by Fanbois of all things apple!
I like my apple products fine, but the PlayBook kicks arse!
