the iPad isn't worth the hassle for note typing as a touch screen will be awful to type fast. If you're going to spend the £500, I would honestly save up and buy a 11" Macbook Air [£730 student discount] (or if you want a PC OEM equivalent). The physical keyboard attachments are all well and good but they're expensive and I'm sorry but iOS isn't a good experience if you want to use it as your main use for university. Windows 7 and OSX are significantly more productive.
To me, and most people, the iPad can't replace a computer yet.
Don't buy a netbook, for the love of god. If you can't afford an ultrabook then buy a cheap laptop. Netbooks are awful.
