What is the best free software to learn touch-typing?

Features it needs to have:

• should NOT display the keyboard layout on the screen!
• should give detailed statistics which actually measure progress (for which key do I have the highest error rate, graphs showing how typing speed improved over time, etc)
• should enable me to actually learn touch-typing in about one long weekend were I don't do much else than learning to touch-type.
• it would be very good if it were possible to load a text-file and the program will use words from the text-file for the exercises as well

My goals are: at least same typing speed as I have now but which touch-typing, want to be able to look at the screen only when typing

P.S.: EDIT: I forgot to mention, I'm using Win 7. And I know what the Dvorak and Colemak keyboard layouts are, but I'm not interested in them. My question was with respect to standard US keyboard layout.
