I never have enough storage space, currently there's a 320 GB HDD in my MacBook Pro and within a year I filled half of it, mostly with photos, PSDs and Adobe Creative Suites. I really need a lot of space so SSD is not worth it for me, although I would love to have faster storage. If sometime soon a 1TB SSD becomes less than twice as expensive as a 1TB HDD, then I would consider one (not going to happen though).
I think SSDs are future tech and that their price isn't really worth it today just yet. I really hope computers will move away from moving parts soon though, and we could have an entirely solid state computer. All we need to do then is figure out how to get rid of the fans and the optical drive, and voila! Can't see that happening soon either though![]()
Again you are making the same mistake that others do. Your Macbook Pro not only has USB ports but it also has FW800 for adding as much external storage as you want. I'm sure you'll counter with "I don't wan't to carry external storage" but the fact remains those that don't want SSD tend to willfully ignore the performance advantage and frame the discussion on absolute size which is somewhat interesting to some of us.
BTW SSD really help with programs like Creative Suite. This was from a couple of years ago.
