The former layout was alphabetical and it was because the typewriters jammed up if you typed too quickly. You get the idea though.I have to disagree with you on this one, because I believe (I was only told this some time ago, i'm not sure if it's true) that QWERTY was created to actually SLOW people who were using typewriters down, because there were health and wrist issues with many people who were using the former default layout, which I believe was Dvorak.*facepalm*
I'm not an idiot, I know why the layouts are so.
The pros still outweigh the cons - I don't want to have trouble typing on any keyboard that isn't my own, and changing the layout isn't always an option. Unless you're seriously into typing quickly (who is?), it really doesn't make a difference. Due to this, I'd even go so far as to say that qwerty is better than dvorak.
Simply saying 'QWERTY sucks' makes you look foolish.
Heres a little fun fact about QWERTY. Note that the word "typewriter" is typed only using the top row. That is not a coincidence.
