The new HP and Treo look AWESOME!
I experimented with the Kyrocera 7135 and found that anything larger than a phone is a friggin pain the is A$$ and I usually need my PDA while I'm talking on the phone to grab info while I'm talking so I can create the illusion that I know what I'm talking about

.
I know headsets are an option but once again if I forget the earbud I'm back to square one again, not too mention that I'm always stuffing a phone in my pocket which leads to broken screens. If I was a suit I would have one surgically implanted on my face.
