Hi Guys. I'm new here and have a pretty simple question. I'm wondering what I'd give up by getting the lower-end 2.0 GHz macbook over the 2.2 GHz mid-level one, strictly in terms of lost computing power. I realize I'm losing the superdrive but that doesn't concern me. I waited for the SR mini-upgrade so I could get 4GB ram down the line, but it didn't have the Canadian price drop that I was hoping would come with it. This leaves me in a bit of a bind. I want to keep to a $1500CAN budget with 4gb ram and 160 or 250 gb hard drive upgrades done myself. The mid-end would put me over that number. I'll be using the computer for mid- and high-end audio stuff, some photoshop work, very basic video editing, and everyday stuff. I usually have like 6 applications open and running at a time, with varying amounts of CPU/memory load. Am I going to be losing much by going with a 2.0 vs. 2.2? Benchmarks would be cool to see but mostly I just want some opinions. Thanks.
