Okay, first; how do you tell the computer to associate .pdf files with acrobat? I have acrobat on the computer (I'll be getting Creative Suite 2 premium shortly ) and when I try to open a file on the internet, it asks me what program I want to open it with, and my only option is preview. When I download a .pdf file, it won't associate it with Acrobat unless I tell it to Preview sucks. Second, and I guess this question would be best answered by a black macbook owner....how do I clean it properly. I know this may sound like a stupid question, but how do I do it safely. It seems to be a bit more fingerprint-prone than my old Toshiba. I tried once with toilet paper and just water, but that seems to just spread out whatever I am trying to clean. Any mild cleaners that would be safe? Thanks I'm loving this thing more and more every day!
