First Apple I ever used was the LCIII way back in 1993. Thereafter, there was a period shortly after when I used legit (and crappy) Apple clones. Of course, those weren't Steve Job's fault since he was absent from the company at the time.
Anyway, 18 years on and having gone through iMacs, iBooks, MacBooks, PowerMacs, an iPhone and an iPad, you kinda feel "invested" into the life and times of Steve Jobs.
So yeah, today Steve Jobs passes on. Looking at that pic from apple.com gives me a weird and unnatural feeling of, quite possibly irrational, loss for someone I didn't even know personally. But if you use a lot of Apple products, you might know what that feels like.
