I've used Windows Computers ever since I was 4 years old. Once I went into Elementary school, that was my first experience with a Mac computer, (5 years old). The design of the iMac amazed me since my grandfather had these beige 'boxes' in the house. I grew up always thinking Mac was for schoolwork only and preferred Windows for 'fun' activities. Now that I'm older, and had my own Mac for almost 3 years now, I have a better understanding of both OS's.
Windows is great for games... And games only for me. Once I moved to Mac, I did miss playing MMO's and demo's of games that I could play on my DELL. Even though my Dell Struggled with a lot of games because the Graphics Card was crap, I still had fun.
Mac is just plain gorgeous. Once I booted up my Mac for the first time I was just overwhelmed and happy. My Mac hasn't crashed or caused me any problems since I had it, unlike my Dell. Within the first 6 months it had a Virus and crashed, and within a year, it slowed down immensely... This irritated me greatly, so 5 years after dealing with a slow, always crashing Windows Desktop, I finally got a iMac in 2010. Will never go back to Windows as a primary.... However I shall use it as a gaming tool.
