A decade of Mac
A decade ago I booted up my iBook for the first time and ever since have been an OS X user. Kudos to Bryn for encouraging me to make the switch and for making the iBook bearable by slotting in another 512MB of RAM. Can't say it has been easy sailing the entire time but I'm quite happy to not have had to deal with Windows issues.
That iBook G4 was followed by one of the first Intel Macbook Pro's, an iMac (2008) and then a Mac Mini (2012).
