RIM, whatever you do...
...hang on to the guy who designs your hardware.
Every time I get angry at the OS on my Torch, I consider the other options - and can't think of one that can take bangs, slams, drops, long drops, partial immersions, impacts large enough to pop the battery off, and gouges, and still have barely a scratch on the screen... or one that goes two days on a charge with heavy data / phone usage... or one with a camera light brighter than most flashlights... or a speaker - oops, stereo speakers that actually function - loud enough you can prop it on the window sill and listen to trance music while doind the dishes...
Or a camera that doesn't suck...
Oh, and a physical keyboard on which I can type 30wpm.
The playbook hardware is equally excellent, and the speakers are better than any laptop speakers I've heard. And -its- OS is very good; bezel swipes are so natural to me now I can't imagine using a tablet otherwise. It just needs better third party software... which, of course, requires success, which requires third party etc etc...
It's really too bad. Put a decent OS in the phones and decent apps on the playbook, and you'd be golden. Assuming anything could possibly override he selffulfilling 'doomed and sucks' perception now.
