Features of Windows Phone 7

+Positives
It’s Live! Windows Mobile 7, a.k.a. Windows Phone 7!
Looks like Zune UI, rumor correct, though everything is live. Build in Facebook integration, beautifull backgrounds. Xbox Live integration is there. Amazing!
“We want the user to be in the center of the of the experience!”
“Every Windows Phone will have 3 buttons as the Phone hardware … Start … Search … Back”
“Devices will have large Capacitive Screens”
New device being shown, no HD2! Totally new device, I don’t recognize it.
What you see on your home screen are ‘live tiles’, they are connected to the internet. They update automatically when something changes in your live. Contact photos are updated from Windows Live Spaces or Facebook.
You can follow people in these tiles, they update when those people update their own profile.
You can put playlists, people, applications, photos, just about everything there in these tiles.
Windows Phone Calendar will have multiple views, agenda view, day view, month, etc. Also it will show more than one calendar, Windows Live Calendar and Excange. Personal and Work related will show different.
Windows Phone 7 can detect addresses from plain text! You don’t have to copy at all, it wil automatically link it and when you click it, Windows Phone will map it.
All Windows Phone’s will be Zunes, it will have full Zune Software installed on the device.
Difference being 3rd party experiences can be integrated into the software, like Pandora.
Synchronizing will be indeed by Zune Software, another rumor which proved to be correct. Sync Music, Videos, Pictures, etc. Just replaces Windows Mobile Device Center.
Now going to the last hub, about games. Maybe ‘Xbox Live Hub’?
Wrong it is called ‘Game Hub’, it will feature Xbox Live though. You will be able to view all your friends from Xbox Live.
Achievements will be available to Windows Mobile Phones? Not said directly, but he said ‘You can view achievements she got on the Xbox or the Phone’.

-Negatives:
Well as I can see, no multitasking, no cab installation, even no file explorer.... that thing is just for the consumers.

-will be updated regularly
