VERY clean and still under Applecare until April 2008. I upgraded to 3GB of ram. Everything else is stock. You can see all the specs
here. Everything is easily upgradable if you choose, but I've used it for graphics and video and its very fast -- I need a portable (just bought a MBP).
I'm the original owner and its been in a clean, smoke-free home office. I have all the original packaging, software, keyboard, mouse, etc. $1050+ shipping. Please no low ball PMs, its a nice machine. Pics to come.
(ps. I'll save you the research -- they're going for $750-1200 you know where at last check, BUT that is WITHOUT Applecare).
