Interesting. To me, a USB is absolutely mandatory. Installing updates, transferring files, storing projects, transferring photos or loading drivers, connecting external devices....especially if there is no hardwire cat5 connection.... I spent a few hours last night, and have been able to synch documents, photos, movies, etc., using iTunes. I actually expected it to be more of a pain than it was. Setting up all my email accounts wasn't too difficult either.
Now, this is just after a few hours - I'm on "mini-vacation" the next 2 weeks and plan to look at it heavily
