Skip on the tablet(its a big waste of money and a real no no) and go out an buy an Air. The non discount start price for the 11 inch MacBook Air is £749, you can probably get it for cheaper using the student discount. If you want a tablet AND a laptop, maybe the Surface Pro 2 or 3 is your best shot. On student discount, you can get the Surface Pro 2 for £512, if you throw in the keyboard, it will come to just over £600 though you only get 64GB of memory so maybe an Air is a better choice
