Too minimalistic...
they need to point out more featuers that set it apart.
Like if someone texts you an address to the bar they are in...in a WP7 you can just click the address and it auto pulls up the location in MAP with 1 more click for directions.
On an iphone, you have to click and hold on the text, set the selector so it is only the address, copy, go to main screen, open maps, paste location, and get directions from location.
*Just found that out last night as I looked up the bar I was going to...clicked "Share" on my WP7 and texted it to my wife who was driving to meet me. She called me and made me give her directions because she couldn't do all that click/copy/paste while she was driving.
