Learn Colemak [1] instead. The change in comfort when typing is incredible. The difference in how much you need to move your fingers when typing is big. Typing with QWERTY feels you moving your fingers all over the place as fast as possible; typing with Colemak feels like letters flowing off your hands. Whether it is faster I do not know (obviously after years of using Colemak and rarely using QWERTY I type faster on Colemak, although I can still touch type on QWERTY -- something that most Dvorak typists seem to lose). The big difference is with comfort. Colemak is also much easier to learn for programming if you already know QWERTY because the punctuation (and some of the letters) stays in the same place.
