I decided against a MacBook Air iMac Duo. Im sure this laptop will be great for my needs however is it worth the $300? I am upgrading the hard drive from 250GB to 320GB 7200RPM. Is the GT graphics worth it? This will be my main machine along with my iMac G3 thats only good for internet and light photo/music. The hardest thing it will do is burn dvds and maybe light games and some light video editing. Also I haven't paid attention to the pro line any hinge screen issues etc? Has anyone really got 8hrs of battery life that was a big role in my decision.
