Up until now I have not had a good go of a device running Windows Phone 7, so I can't give a good opinion on the OS or the handsets the OS is running on.
However a friend and fellow blogger has put together a list of his top 10 apps available for the OS, so head over to his site to see what applications he recommends.

I am always interested in your thoughts so if you have any comments or feedback then please feel free to add any comments, or you can mail me here.
