As much as i like the pad, it is not a substitute. Like others have already said, if you need this to get by in school, get a cheap laptop.
You will likely need the convenience of a full keyboard.
You will like want to swap files with peers
You will likely need to print to whatever available printer you can find.
You have a fair likelyhood of theft. A low end laptop is a lessor target than a pad. And you wont feel as bad when it happens.
You have afair likelyhood of beer spilling on your device. You will hate your firen less if its is a low end laptop than a pad.
A low end laptop will cost less than the pad plus accessories you would need.
