I have a 1.66 Core Duo Mini (superdrive) in which i upgraded the Ram to 2 GB and harddrive to 320 GB (the old hard drive crashed). Is it worth getting the new mini ($599 model) with the 9400m? Or should i just wait out the mini i have for another year or so until it is way behind the times? I figure the $605 (student discount +tax) will be offset by selling my mini (maybe $400). So is the $200 upgrade worth it? i will probably upgrade the RAM myself to 4 GB for ~$68. PS - I plan to just do a swap out one evening while the wife is asleep. i don't think she will know.
