reading reviews linked from OSNews I get the impression that the iPhone is a OK or maybe a good PDA and a bad phone. Also calling it a smartphone is just exaggeration, you can't install 3rd party software so it is not a smartphone, period! Web widgets don't count. EDGE is just a joke - the reviewers basically say that web and email is unusable using EDGE.
Comparing the iPhone UI to WindowsMobile is a really cheap move since the WindowsMobile UI always sucked.
Apple claims to have the best smartphone that is currently available but the iPhone lacks very basic features found in other top devices like: an expansion card slot (e.g. SD/MMC) and GPS receiver.
iPhone I DON'T want one!
