Windows Phone 7 is a PRETTY OS. Beautiful even. Android is just plain ugly. No one picks up an android phone, starts playing with it at the store and says 'oh WOW'. Its a confusing, unintuitive UI. Badly designed, just like all Google software. Most of it looks like it was designed by an Engineer rather an a UI expert /designer.
Palm's Web OS is also so beautiful. I am worried Windows Phone 7 will go the way of Web OS..beautiful but with not enough support from the app community to make it a truly great OS. Web OS is similar to WP7 at launch in that it lacks features common in just about every other phone. No Copy Paste? Seriously?
Also the hardware is relatively unimpressive thusfar. The WP7 phones are just meh. The Palm Pre was a beautiful design. It should not have been launched right now. They obviously rushed it for the Holiday season. It needed another 6 months-year of development to make it truly amazing and fully functional.
I am hoping that WP7 ends up being successful, we need something BEAUTIFUL as an alternative to iPhone..Android is ugly as sin, plain and boring.
