Just received my new macbook today. 4 GB RAM, 2.4 ghz, and SSD. I was very interested to see how this machine would run with SSD, and so far I have not been disappointed. In one word, fast. Benchmarking doesn't quite do justice to how SSD elevates performance in a notebook. For one thing, I've been using it for 4 hrs open on my desk and it's cool to the touch. The fan has never been on and even with my ear pressed to the case I can hear nothing. Boot time is blazing. Apps snap open with a click. I can't wait to install vista via bootcamp; with these boot times I will be able to switch back and forth as needed with virtually no delay. My wife has the new MB with the hard drive...a great machine but the difference in real-world performance with SSD is palpable. Bottom line, expensive but worth it. No doubt prices will half in the next 6 months but that's being an early adapter. I'd be surprised if you can buy anything but a low end notebook without SSD within a short time except in special cases (ie the need for very large drives). I can see a whole new market for SSDs being created by Apple given the ease of swapping drives in these new macbooks.
