I'm still using my 2006 white Macbook as my only computer (1.83 GHz C2D, 2GB RAM, 320GB HDD). It does pretty much everything I want, except play games (I use an XBox for that). I played with a display base-model MBP the other day and was impressed with the build quality and upgrades (nicer screen, trackpad, built-in SD slot) but I can't really tell if the performance increase is night-and-day just based on opening a few programs. The most CPU-intensive programs I'd use are Lightroom, Garageband and iMovie. The time it took to load up Garageband and iMovie were not much faster than on my current MB. In fact it seemed the 11" MBA next to it loaded them up faster than either system. As I hadn't had the chance to really use both programs under the new MBP, I just wanted to get an idea of what tangible benefits I can see with photo/music/video. I was a little disappointed with my first impression but as I hadn't tested the programs further so I'd like to get others' opinions. Thanks.
