I've seen the touchscreen hack but i wanted to take it a step further.
I'm going to get a touchscreen, add bluetooth internally....
then i'm going to mod the case to make an HP Mini Tablet!!!
I started playing around with it tonight and here are the pics of the layout i'm probably going to use.

the screens not attached!!!

It's up and running Windows 7... got the speakers resituated and the webcam too.

a worse pic of the screen, better pic of the internals.
I ordered the 10.2" Touchscreen kit from mydigitaldiscount.com and when it comes in i'll have more info. i have a few vids of it as well that i'm gonna post to youtube, I'll put links in here. stay tuned.
