I love my iPhone.
No Flash support - makes some websites useless
No PDF support - Clients can't send me PDFs for review
Can't run multiple Apps at one time (most phones don't though)
Have not paid for an app yet, as most of them I don't find all that usefull. Don't get me wrong, there are some really good pay apps out there, but for my purposes, I don't need them.
Some of my favorite free apps:
The Weather Channel
SketchBookX (great little drawing app)
Eurosport - Helps me keep track of F1, WSBK, and other racing (good if you like soccer too)
SportsTap - Helps me keep track of NHL, NFL, and American racing
I won't list all the games. I download free ones, play them for a while, delete them then load more....
Oh, I also use the preloaded Maps app all the time.
