This should be a very >> fast machine but I'm actually unhappy about it. I've been playing with a Macbook with stock RAM (512M) and CoreAudio crapped out every 5 seconds with large streaming instruments etc. . I just now popped in two 1G DDR2s...the performance is stunning. Change a 512M chip to a 1G and I think you will be pleased. -Jeff Agreed - I have never had a powerbook/macbook work well with 512 RAM configuration. YMMV. Gareth http://www.garethjones.com
