Hi Guys First post here. Back in December I bought a lovely 2.53ghz unibody macbook pro 4gb ram 9600gt 512mb and 320gb 5200 hdd and apples 24" LED screen. Its great, fast powerful and quiet (and sort of portable) I used to have an imac but thought i can replace it with this set up as if I need to use it round the house and out on the road I could (i didn't do allot of traveling then) Now tho I do allot more traveling and need to take a laptop to work, so i got the new macbook air 2.16 128gb ssd. Now the problem, it is twice as fast at opening applications and files. maybe it doesn't have the raw power and graphics the macbook pro has but it feels so sluggish now in normal everyday computing. So what can I do? put a SSD in my macbook pro? If so which one? a 256gb is more than enough storage i think if not another 320gb ish ssd? Any ideas guys?
