You can, but fedora 10 as it sits is not very touchscreen friendly. a frontend allows you to have a nice easy touch friendly interface to your computer, media, gps, anything/everything you want. Ever tried to use a computer while driving? Trust me when I say, don't. It's a good way to get killed. While still dangerous to operate while moving, a frontend makes it slightly safer too.
Btw, if you're looking into linux check out nGhost
