The iPhone is obviously very cool and very sexy. But it is not so much a phone as a really good Newton that makes calls and emails. Not to be a buzz kill, but I can't fit it into my jeans pocket and I have no idea how to keep the screen from being scratched.
I can see how this could be a VERY handy device - particularly for business executives at the level that don't often sit at or carry a computer during the day.
I, however, and stll looking for a combo solution. If the iPhone had a data card that I could slide into a small clam shell unit (or shuffle like thing) - keeping the same phone number and data, but with much less bulk, I would buy it in a second.
On another note: there is an excellent article on the Business Week site that cedits Apple for raising awareness of Design's importance in the business world. An excellent article to give to a client or boss.
