Finally got my build to order macbook!. M7 with 512 MB. In my honest opinion, the speed is very comparable to the mid 14 15" Macbook Pro I was using. I do not code or edit video. I use a command line terminal called iterm2. I use office. I use chrome. Email. iTunes. iPhoto... loaded up as a fresh install, very snappy performance. The SSD seems to really make up for the lack of cpu if you are not needing raw processing power. The wifi is very slow to connect, not sure what is up with that. Overall, very satisfied. The screen is amazing. The keyboard is not nearly as bad as some people make it out to be. Portability is astounding. It is like an ipad that runs osx!
