Over the past two years, I've been using OSX to mainly manage and edit photos. Poor Jason was the unlucky bloke who was stuck with the task of installing Aperture on my iMac. He spent about the same time installing Aperture as I did Windows on my Toshiba. OSX and Windows - they're both end-user torture devices in terms of their stupid installation hoops. So I was definitely able to sympathize with Jason as the vein down the middle of his forehead became more and more prominent as Aperture's install ran into the wee hours of the night.
Fortunately, history didn't repeat itself during the Ubuntu install on my new workstation. The install instructions were very easy to follow; no "doh" moments to speak of. But most importantly, I spent only thirty minutes total on the project of great disdain. I got to go to bed on time, and I didn't wake-up pissed the next morning because I had wasted all of my free time the night before. The install went so well, in fact, that I'm almost looking forward to reinstalling for the fun of it next Ubuntu release.
