Setting up Windows laptop

Finally configured Windows 7 on my work laptop to look like my mac(with all those cluttering shortcuts hidden). I even bought the Microsoft Arc keyboard (which is small and looks like a mac keyboard). In fact, I have to say I like the windows 7 setting better, though the DELL laptop looks just too bulky and ugly compared to the sleek mac power book.

P.S. all the mouses I tried on mac (including the nothing magic Apple magic mouse) were not responding as smooth as on Windows. Is there a thing between Mac and mouse? Or should I use their track pad (that's yet another spending).
