I was in the same position last winter- waiting for the Intel laptops to be released...I bought a mini to hold me over until the macbooks came out.

I've had my black macbook since May and can't think of anything it can't do that a newer, more powerful model would that I would really need. Now I use Adobe's programs(still not universal but good enough for me), run WinXP in Parallel's, run a sign business with an overly expensive sign program and do all the usual photo, music and websurfing. I have no problems with speed, memory or the integrated graphics.

I really think computers have gotten to the point where they are plenty powerfull for 90% of the users out there. It might be tempting to wait for the next OS upgrade....but that could bring it's own large can of worms...we won't know till it happens.

If you buy now you'll be happy sooner...then can upgrade the OS when you see other's experiences(horriffic or pleasantly smooth or somewhere in between). You'll be glad you made the switch either way.
