i use a good laptop right now. Yea it works great. I just think it would be awesome/convenient/advantageous to be able to have a tablet right in front of you to monitor at any time. I do a lot of 20 hour plus trips and it would be pretty cool to be able to monitor my engine that simply.
In addition you could pay the monthly fee for WiFi and have google maps and music and unlimited resources at your fingertips. seems like it would be pretty ****ing cool.
