Yep, I said it. I've used Windows since version 3.1 was out. I actually switched from DOS to it a very long time ago and I haven't used a console for a long time now. Windows was my home and my office for a very long time, until last year when my W7 laptop crashed and once again, most of my non-backed-up info died with it. I just decided I would change and try to see what happened if I got a Mac, so I went out to my nearest Mac Store (I was visiting Austin back then) and I got me a Mac Book Air with Mountain Lion.
Boy was I surprised: I switched it on and it booted in like seconds. After that, setting it up was so easy and so fast that in less than 10 minutes I was up and going through my corporate webmail. After realizing I could use safari (I was worried it wouldn't run as IE did my whole life), I went straight ahead to try and find new updates for the system, and there were none. Now, that was surprising too, because every time you install windows you have to download like GBs of updates and patches.
Another thing to say about Mountain Lion is that Multimedia is really there. You may have to update one or two things, but running or making a video, using iTunes or your favorite photo editing software is really easy: it doesn't kill your OS like what it happens in windows. I actually used my Mack Book Air to run "heavy" software and the machine never heated up...which took me to a conclusion: the technology is better, but also, the software runs differently on Mountain Lion.
A great investment it was!
