David Pogue of NYT has a nice write up on Windows Phone:

"Windows Phone 7 shows some real genius, but it is missing an embarrassingly long list of features that are standard on iPhone and Android.
Ready?
There's no copy and paste. No folders for organizing your apps. No way to add new ringtones. No way to send videos to other phones as MMS messages. No video chat.
Like the iPhone, the Web browser doesn't play Flash videos on the Web -- but it also won't play the HTML5 videos that the iPhone plays, or even videos in Microsoft's own Silverlight format. So, no YouTube, no Hulu, no online news videos.
But the WP7 is a 1.0 release in a good way, too. It's a complete rethinking of app phone software design. Somehow, Microsoft has pulled off the inconceivably difficult task of coming up with a fresh, joyous, beautiful new software design that doesn't look anything like iPhone or Android....."
So as he says, Windows Phone is one to watch. Some of the better people at Microsoft are now in there. Coming behind two successful competitors is hard though. I don't know if Microsoft is still charging for the OS. If it is (and Google doesn't), then I don't think it will ever succeed. The PC world is a two-horse race. Can this market handle 3+? I am not sure.
Personally, I think any OS that doesn't offer multi-tasking is not an OS! So it certainly is not for me right now.
