ok one question, when are you planning to buy it by? i assume the summer right... well the MBP line is going to be updated soon so maybe youll see the SB i processors! wait on it, dont buy as soon as iPad 2 comes out! you never know!!!
The mac mini although not an i series processor is still a good machine. I use mine to run as a media server. Works really well when hooked up to a tv with plex and front row.
The ipad 2 will be a far better machine. I still think that the iPad 1 is crippled in terms if what it should be.
More Ram and a camera are just no brainers. A better processor and connectivity with a better screen will be a bonus if the eventuate.
For you I would think about a mac laptop- a better option for uni.
Well like i say, i'm saving now, and ive got this personal opinion that they're gonna announce it round late jan, feb time, with a release in April, so plenty of time. Then i'll get the new Mac. But I can't personally see the point in having a laptop AND a tablet. But the new yet-to-be-seen features of iPad 2 could change that
