During CES 2011 the new Windows Phone 7 update that is due out was mentioned several times and it appears there are two updates heading our way.  One is a smaller update that will include the addition of copy and paste, some bug fixes and performance enhancements.

Well the performance enhancements look like they will be very welcomed based on this video showing two Windows Phone 7 devices side by side.  One has the update while the other does not.

What a difference this update is going to make.
