About why I feel more "productive" on Windows than a OS X.
Don't take it to mean that I'm "unproductive" on a Mac in a negative way - when nothing can be further from the truth.
I have friends who use both and feel the same - hidden registry files in OS X and the cute icons and multitasking combined with Expose and creative apps creates something called the "OS X Procastination Curse."
I've seen it in myself, and friends in college.
Basically, OS X is engineered and designed in a way that doesn't put you in a productive, business-like state of mind.
If you're in a creative field like graphic design/music/ etc, then the effect is null -- but for right brained people with scientific and business minds, OS X has an effect of making you want to watch movies, browse casually, listen to music, and look at cute icons and effects.
It's not a NEGATIVE thing, so much as, say, I have a deadline, and I feel somehow like I focus more on a project and am not distracted on Windows 7 then on OS X.
On OS X, I just click on icons and play around instead of focusing on writing a paper, or word processing, or doing a spread sheet.
I believe OS X induces procrastination for business/serious disciplines.
Something about the cute icons.
Definitely some subliminal programming
