Well, I installed World of Warcraft, and I wasn't able to successfully add the other 512 megs of memory (I need a smaller screw driver). It runs adequatly, but I suspect it will run a lot better with extra memory.
I have all of the settings pretty low in the mean time. With that said, it looks absolutely gorgeous. The screen on this thing is amazing. Every thing looks far better than I could ever have anticipated. I don't find the screen to be really really bright, but it's adequate. But the resolution, and quality is just amazing.
I'm also impressed with the keyboard, which I'm actually finding more comfortable than a regular keyboard. They did a great job.
I can't wait until I can install Tiger on this thing! This is going to be a great laptop for all of the practical things I want/need to do. I think I won't be using either of my desktops (mac and pc) much anymore.
