In my case, I happened to be in NYC for business and if you've ever compared the prices in Europe vs. the US you know this was an opportunity I couldn't pass up on
I was very much in doubt between the 13" and the 15" w. high res/matte screen. However, this is my first Mac and I wasn't sure I was going to like it. This one was $1200, the 15", with the matte high res screen was $2600 (the Apple Store only stocks the faster CPU w. matte screen). I like the overall dimensions of the 13" better (this one will mostly see "surfing from the sofa" type of use).
If OS X grows on me I may throw out my Windows PC and replace it with an iMac or Mac Pro to do the heavy lifting.
Is there a list of key combinations somewhere? I was kind of shocked to see there was no Backspace, PgUp/Down, ...
I've discovered some combinations like Fn-Delete, Option-Up/Down now, but a comprehensive list would be nice.
