My first post was about my impressions of the macbook where I spent some time and care at the Regent Street Store. http://forums.macrumors.com/showthread.php?t=1872293 Today I went back to try it again to see if my impressions changed. I went to the Covent Garden store. They have lots on display now. The GUI really does lag and stutter comparwd to the Air and Pros. Typing doesn't get easier for me. It hurts my hands after a while and it's inaccurate. The MBP and Air keys work better for me. They are very light though!
