MrClass wroteI am left handed too! I use a Microsoft Sidewinder X6 keyboard for comfort and fast typing (the buttons have a nice bounce back feeling, and u dont need to push the buttons hard either). The keyboard is also backlit in case you need to type in the dark.
And is it most comfortable to you compared to other keyboards, considering the fact that you're left handed too? Also do you need to have it in a particular orientation, like left handers usually rotate their papers when they write?
