In my formative computing years, I grew up with a Mac, happy. Then iTunes came along and I wasn't happy, unable to copy my music. This pushed me over the edge into the crazy land of Linux and Free Software.
Now, after seven years, I am reunited with a Mac laptop. It's at my new contract in the heart of TheSmoke, and funnily enough, it's with a Ruby on Rails team. I am gleeful and unbesmirched by guilt at trying out Proprietary Trinkets. I have dusted off my old TextMate license, installed the missing drawer, the RubyBlue theme, the HAML and Markdown bundles. Heck, I've even had a pop at Coda, the text editor de jour de mac.
Funnily enough, what I like most about my newfound Mac experience is the two-fingered trackpad scrolling (odd how touchscreen technology has fed back into the humble trackpad) and the global Spotlight find (alas, no more real need of QuickSilver).
