I have a 1 gig powerbook with 768 Mb ram and looking for a really good 
piano. I've been looking at the Giga stuff and see a 5 gig piano and 
the Bosendorfer (hope I spelled that right). I have no idea as to what 
is a realistic piano to get. Am I biting off more than I can chew with 
a 5 gig piano? Does it still stream off the hard drive? Do I need a 
wack 'o ram? Will that limit what other instruments I can use? Should I 
just go with a 1-2 gig piano? Obviously the more layers are sampled the 
better the piano sound but I don't want to overkill sending sparks 
flying from my computer.

any thoughts on cool pianos for my setup?

thx, Simon
