我用. WP7 也用.

不相信desktop版可以直接运行。
实际上完全没有必要。至今没发现需要什么程序没有。

WP8应该可以和win8兼容很好，但由于WP8直接同步到skydrive，居然没有任何原因需要连接PC的。

From WP7.5, Windows Phone provides a very good alternative to iOS with simplified Metro and redesigned gesture control. I like the physical camera button that can wake up camera without unlock. Neigher iOS or its student, the Android, can compete on this factor.

Another advantage is the on-screen notification, usually set to Outlook Calendar, and up to 4 icons showing how many new messages are popped in.

I will hesitate to move back even if iPhone gives me 4" screen. Android is just too complicated to look at, tiresome to use and boring to remind everyone of iPhone.
