Hi All, I am looking to move to MAC after losing hope on Windows improving anytime soon, and need a little advice to help me decide on what to get. I am not a heavy user as I have a work laptop as well on which purchasing decisions are unfortunately made by the IT guys. On my personal machine, I have all my media, some light-ish office files and comms such as email (on Tbird), skype, the usual. The problem is that I like nice screens with lots of pixels. My current laptop is one of the last-off-the-line Thinkpad T60p 15" with 1600x1200 matte IPS panel. Its 3 years old and I hold on to it purely because of the screen. I travel a fair bit, and take a lot of pictures with my 450D so having high res really helps. Purely for this reason I am inclined to go for the MBP 17. However, I am concerned about portability. Does anyone use the 17 inch MBP on the move regularly, or move it around much, even if only in a car-plane-car-hotel scenario? I dont plan to have it on me all day. Also, is there a significant real life battery time difference between 15 and 17? The main question however is this: 77% more screen vs more heft in real-life use. Any comments greatly appreciated.
