I am trying to decide which HDD I should get in this thing….cost aside for the moment. It would be interesting to see how much space is left on the 64 GB SSD when the computer arrives….I would imagine that there is probably about 60 gigs of useable space, count 15 for leopard and ilife after trimming useless apps (garage band, I’m looking at you, maybe iMovie too), and extra languages. Plus I would like to have most of my music on there, because I will probably want to surf the web and listen to music…lets say 15 gigs if I select my most liked music. So that leaves 30 gigs….then I want some of my more recent / impressive pictures, 5 gigs, plus another 5 of some movies/videos for that rainy day. You’re now down to 20 gigs….lets say you want office, that may be like 2 gigs. So now you have 15-18 gigs to play with…. I am sure it is workable, but I would really miss the added 15 gigs of buffer that the 80 would afford me…..but from the sound of early reports, the SSD sounds much faster, which would boost my enjoyment of the system, since you would notice the speed boost all the time as apps booted, and so on. I think that clearly a good option would be, as people have mentioned, to get the 80 gig now and swap out later for a SSD once prices come down (i am guessing 64 gig drives will be 1/2 to 1/3 the current price one year from now). But you just never know... what does everyone else think? Could you make 64 gigs work for you? how much would you trim off the OS?
