Regular keyboards are why many people end up with wrist/hand/shoulder/etc. pain. Perhaps going as "extreme" as something like Glove80 is unnecessary for most, but I wouldn't recommend a regular keyboard to anyone that types at least a few hours a day.
I'm really glad I took the plunge and switched to a keyboard that I could program to move the action away from my pinkies (I moved the character blocks outward and got real creative with the two new columns between g and h).
Had I waited longer I think it would've gradually dampened my enthusiasm for code, just by association.
