In 2007, I made the switch.. it's been a busy year (since March)..
I bought my first Emac and titanium laptop (company auction) and fell in love with Mac.
Like those so much, I bought a used iBook G4 (upgraded the ram and hard drive)
I went on to save my pennies and got the new iMac 2.4 24", (again) liked it so much I had a small conversion party at Xmas for my wife and son (2 more iMacs).
Now I am dangerous... I have all this tinkering knowledge (from using Windows for 20 years) and I can show all of my friends that I don't have to do that with my macs, it just works! If XP or Vista worked as well as OSX, I don't think I would have been as willing to switch. Curiousity got me, and I am not looking back. Elvis has left the Microsoft building 😀
