Let the hive mind of Engadget get that for you.
"I'm in the market for a new phone and money isn't a limitation. I'm also not partial to any particular US carrier, but here are some of the features I'd like to have: WiFi, GPS, good coverage in lots of places, push Gmail (a must!), physical keyboard (a must!), a touchscreen, decent battery life and a relatively slim body. And please, nothing that has a fruit logo on it. No offense to the fruit fans, though. Thanks!"
It should be obvious that this is a version of OS X specifically tailored for the phone. Call it "OS X mobile" if you will.
Hopefully they will release mobile office apps for OS X mobile, but they didnt say anything about it yet...
For one thing, everything is touch screen driven, so all the interfaces would probably have to be redesigned (unless you want some half-assed apps)
