I am not very computer literate so take what I say for grain of salt. But I like to camp and tour on a bike, and sometimes I have to take a computer, which always left me a bit concern with vibration and jarring and possible getting wet could damage a computer. So instead of taking risks unnecessarily I opted to get a Panasonic Toughbook S10, this bad boy can take a 30" drop and anything spilling on it's key board, the battery will last 12 hours so you don't have to worry about charging it as much, and the weight isn't bad at just a tad over 3 pounds. Panasonic makes even tougher ones, but they cost more and weigh more. They also make a Tough Tablet but why? I like key pads.
