I picked up the i5 128 4G model on launch day, and I am absolutely in love. Brilliant machine. The only thing I keep second guessing is whether or not I should have grabbed the i5 8G model. I am not what you would call a 'power' user. However, I regularly use photoshop, but not while any other programs are open or running (maybe a browser window or something). I have been monitoring the RAM use and it never seems to go above 2.9 - 3.1G. My areas of major concern are: resell value, unforeseen windows update that could eat RAM and the fact that the RAM is static; unchangeable. Appreciate to hear what some of your thoughts are.
