Few things I have been noticing about my new MacBook -- any suggestions to help? - It easily get strange marks on the surface where you put your hand (keyboard, trackpad, etc.) -- I have no pens, or any other objects that can get my computer marked with black marks, but somehow I keep getting one or two small marks each week on the surface and I can't get it off. Anything useful to remove them? I have tried using alcohol and q-tips but nothing seems to help. I believe they are some type of ink or something. (I do wash my hands and I use external keyboard + mouse) Should I get ShieldZone? - Somehow the battery doesn't fit in exactly well. It shifts around when I touch it -- normal? (Battery life is 3-4 hours) - Mini DVI Port - I have a VGA display monitor, and the price for the apple Mini-DVI - DVI adapter is $20. Where can I get some cheaper ones? - I want to install Ubuntu Linux on my computer. Does bootcamp work with that? (Create partition then use Linux disc to install?) Can anyone help?
