We're not stuck with QWERTY. Windows XP lets us switch to Dvorak easily, in Control Panel/Regional and Language Options/Languages/Text Services and Input Languages/Details/Installed Services/Add/United States Dvorak.
You can make it default, and you can set hotkeys to switch back and forth. Unfortunately the default takes over with each app you open, but the default hotkey to switch back and forth is listed as ALT+SHIFT, but CTRL+SHIFT works instead.
A little panel appears for switching, which you can close permanently. Maybe switching with that stays put.
Anyhow, my default is Dvorak and I'll never go back. You can type 500 words on the home row! No "troublesome pairs." I have keycap stickers on my originally QWERTY keyboard, which is pretty mandatory because the one DVORAK keyboard I tried was a klunker.
Here's some info.
