You know, I don't even mind the 2.5" hard drive so much. For me it's the RAM. Judging by what I hear, it sounds like it has two RAM slots. Only ships with 256MB RAM. You really need 512MB to run things without pulling your hair out. But 1-2GB is ideal, at least for what I use it for, which included a lot of Photoshop and InDesign work. Yes, you can just get a couple 1GB chips and stick them in, but that's not cheap. Two 512MB chips would probably be fine for most users, even doing some graphics work, and that's cheaper.
So really, that's my main concern. Not something that can't be dealt with, though. It also only has 1 firewire port, but I guess a hub can take care of that. But basically, it's stripped down, so it's hard to deck out with a lot of stuff.
Looking back and seeing what you're going to use it for, it's probably a great machine for you. Maybe buy a 512MB chip for memory. The speed is fine. Much faster than my current G4, which is as fast as I've needed. Doesn't have a DVD burner, though you can upgrade to that.
If you're looking at switching to a Mac, and you have the monitor, keyboard, etc., then this is the way to go. And man, it's just so dang small!
