I am trying to determine a) what could make the macbook better b) should I wait for the next gen model For starters, 2.2ghz and 4gb of RAM sounds great to me. Here are some observations I have made. I have looked at the MacBook Air and the MacBook side by side, and the Air's screen seems brighter (LED, right?) Also, I want a Backlit keyboard, but I don't like the Pro's keyboard (So pretty much the Air's keyboard). Obviously it could be a little slimmer, but what else could really make this great machine better? Should I wait, or just go with the current model? I know Macbook Pro's are due for an update VERY soon, but what about the MacBooks? Thanks for any info!
