Treo?
While Moto and Nokia release a new and soon to be defective product monthly, and Blackberry continue their path to becoming dinosaurs, Palm has released 5 of the most flexible smartphones ever, at a rate that shows their stamina and usefulness. If you office-types must, Treos have your windows mobile covered, and for those of us who want true flexibility (along with the excitement of hacking/rehacking), the Palm platform will remain the open source flagship smartphone, even after its move to Linux. I've been using a 650 for 3 years now, and am always finding new applications and configurations to tweak it to perfection. Given a little time, like any device worth its soldering joints, you'll end up with a solid, customizable device that any business can afford (I paid $500, but they're practically free now).
Stop tinkering with your E-blah blah-i model crapphones and get serious.
(and btw, regarding the iPhone, which really can't be compared to, well, anything, if you can't type on it, you're just not very coordinated, that's all)
