Well this is my first reveiew I have wrote, and this is also the first Mac I have ever owned. I currently also own a Alien Ware M5550, IBM t42, Asus Z70VA and an HP Dv5000. Hands down this PowerBook blows them all away in ever aspect of computing. I will never own another system now after running Mac X 10.0 on this. The performance is amazing, the quality of build is above and beyond what I could expect from any PC. Everything I seem to touch just goes smooth, from setting up the airport wireless to my network, from installing and running my software, trasfering all of my IPOD music over to this etc etc. I am literally amazed. I got this notebook fully loaded, the only upgradeable options was one more step up in the processor speed, a high gloss screen and 3gb ram instead of 2gb. I paid $2400 final with a nice $200 rebate for students. The entire ordering process, shipping and packing was above the quality I have ever seen anywhere else. I thought it would take time to learn another operating system. I turned this on and It felt I was right at home, everything was so easy, right there it seemed. I will write more as I use the notebook.
