I just recently migrated from using a cell/PDA combo to a Pearl, and it's been wonderful. After a few days of mucking around with it, I think I've worked out the kinks (mostly by finding newer firmware) and am able to use it or organize pretty well everything that I'm doing. I was particularly surprised at how smoothly the transition away from my Tungsten E2 has been - my previous experiences supporting BBs at work had me worrying that the switch would be more painful than it was.
