First off, I have never owned a Mac, however, I own all the iPhones, the iPad, and two iPods, so I am used to that interface however I am not at all familiar with Mac OSX. I could really use some help/tips I should know for when I get my Macbook Air. Also, I would like to know what other software I should buy (if any). I was thinking about getting Microsoft Office for Mac but then I thought I already have Office 2010 for my Windows 7 laptop, so maybe not. Any help would be greatly appreciated!! Thanks in advance.
