Hello, after buying an iPod a few months ago and being blown away by it I started to seriously consider switching to Mac. I do lots of multimedia, including music production, and I'm a fan of great design, so it seems natural. I'm going to college in the fall, which means i'll porbably end up buying a laptop. I was looking at the 15" PowerBook and liked it, but have become concerned that it's due for a replacement, since it lacks things like DDR RAM. Does anyone have any idea when Apple plans to do this? I don't need a date or anything, i'm just wondering if it'll be before the end of August, which is when I leave. Also, does anyone forsee USB 2.0 ports on the next line of PowerBooks?
