What size laptops does everybody use for tuning?

[Halon]

I was using a 12" Dell until it got stolen not too long ago. Now I just picked up a 10" netbook to use around the house, and will be using it for tuning as well. Yes the screen is small but that is fine I can deal with that. What is nice though is the battery life on this sucker is rated at 8.5hrs (in reality probably closer to 6). My laptops before just didn't have that good of battery life, and the cig lighter converters I've had never seem to work all that well.
