Hi! I am in need of installing XP onto my MBP for the purpose of buying stuffs in the internet (the online store does not support Safari nor FF ), thus i'm not going to use it often. I read in the Apple Support website that the min. is 5GB for XP to work basic functions. But the problem is, i need to additionally install Chinese for typing and reading. So the question is, would 5GB still enough? Thanks!
