<--- nonMS employee here. This browser has potential. Viewed on a XV6700 in landscape its pretty sweet. Having spent many years in site design, the opportunity to view a site as the designer wishes it to be viewed is a nice leap for phone technology.
Would like to see a couple features added that I currently don't see....
1. The ability to use your stylus while navigating. (stylus controlled point/drag/zoom would be very sweet)
2. A "thinking/working" icon...
Final small note... I am an avid gamer, but technology exists for so much more. I would much rather carry around a smartphone with VPN, FTP, Browsing, Sync'd Calendar/Messaging/Tasks with an instant on, then carry a laptop any day.
