I just purchased one for my kids. Upgrading RAM was easy, just need a putty knife and a small magnetic phillips screwdriver. It took me about 15 minutes total. Performance is about the same as the previous generation. The Superdrive is crap as others have stated, some Optiarc crap. It's noisy as hell (Like an xbox 360 drive). It only makes noise when you use it though. The 9400m is a plus.
