I would like to get a portable 12" pb as a note taker for college. The MacBooks are a little too big and the air is too expensive, but the pb's are running upwards to $600 and I've read they have heat issues and warping etc. They arnt exactly super light either are they? I've looked at ultraportables like the thinkpads x61, they seem robust and good for traveling and not being damaged but I dont think windows makes bootcamp. Should I spring upwards to 500$ for a pb; or are they not a backpack laptop?
