I originally owned a 15" macbook pro but sold it because I was betting my iMac I ordered would be yellow free but that wasn't the case. So instead of exchanging it I decided to just opt for the return and get a macbook pro. I have two choices now. 15" Hi-Res i7 4GB RAM 500GB 7200RPM GLOSSY I dont think I'd normally choose glossy but I'd be also getting the 24" ACD to match. or. 17" i& 4GB RAM 500GB 7200RPM MATTE (although Im trying not to spend a ton of money, I can upgrade to 8GB ram if I don't get the display. I choose matte because I think the colors would stand out better and the reflection started becoming annoying in certain places. It would cause me to turn the brightness up all the way which of course kills the battery quicker. The size to me doesn't necessarily matter. The 17" isn't much bigger or heavier and I've owned both before. They're both awesome machines. I can even possibly consider getting the 17" and eventually saving for the 24" ACD. A majority of the time I'd be keeping it on my desk or moving around my house. I don't like taking my machine with me everywhere. I've gone without a machine for 2 weeks now and it's going to be probably another two weeks by the time I get another machine so everyones opinion would help me dearly. Doing my design work isn't horrible on windows but frustrating at times!
