I'm sure I could get better acrylic online, but I only needed a small piece. I think I spent $3 on the two pieces I bought, and they're working well.
The touchscreen I bought was from DealExtreme and made for an Eee, so it's not plug & play. I tried connecting it via the touchpad port, because that port does have +5v and Ground, and is 4 pins (I really thought it would work), but got nothing. I rerouted the data lines to the WWAN port and everything is groovy. It would have been nice to avoid solding directly to the motherboard, but all's well in the end.
So right now I have a ton of empty USB ports. Three on the touchpad controller, the webcam port, and the bluetooth port. Problem is I have almost no space in the unit anymore
Today I'm going to finish up the power button and acrylic bezel and hopefully be done!
