I started succumbing to Mac Lust just about two years ago and finally broke down a few weeks later. Today, like most Mac users, I keep my entire life on my (insert Mac model here). I never did that with my Thinkpad. It was more of a “spare” computer. Too heavy to lug around and very wifi unfriendly.
I imagined that I would be what they call a “slider.” Someone that slid back and forth between operating systems. But I almost never work on Windows these days. I sold the Thinkpad and only turn the home Dell on for Windows security patches.
At work, I click over to the Windows side of the iMac to flush email from Outlook (I use Apple Mail now). I don’t worry about Vista because it will never be a factor in my work/play life.
As more and more of our world happens online, being able to get there in a fun and efficient way is (for me) important. My mac is my window and doorway.
