Well.....I'm a couple of weeks into my MAC experience. My intent is to give MAC OS 6 months to win me over, but I can tell you that the shortcomings in this OS are getting on my nerves. USB3 and bluray not being part of the MAC vernacular are interesting to say the least. I do like iPhoto more then I thought I would and browsing is snappy. I like the time machine backup also. I am also an avid user of open source offerings and the MAC platform does not seem to be a friendly environment for these applications. I have yet to be able to print to my printer on another PC on my network. When I go to MAC forums most have seemed to given up and bought a mac specific printer. I don't want more then one printer. It also took two weeks to get my mouse to operate the way I wanted and it took third party software to accomplish this. Really? I might get flamed for this but I think that a MAC is a great supplement to a PC.
