I grew up tinkering with linux since 2.0.x days up until 2.4.x lamenting on how Linux needs to take over Microsoft. Then sudden (legal) blindness hit, and computers were becoming difficult to use. Took a punt on a powerbook 12" at the time, and learned the accessibility features and never looked back. I do 90% of things in a terminal on a mac today, but Windows / Linux is the real limited OS for me due to lack of accessibility features rendering them unusable.
