Отличная русская клавиатура! An excellent Russian keyboard!
When typing Russian I use http://translit.net/
It's very good :)
EDIT: If you want to type some Russian but you're on someone else's computer, for example, then using the above link is great.
Or better yet.. use the phonetic version provided by the OS. That way you can type normally in Russian without having to learn a new map. Very easy.
Some people can't type without looking at the keyboard. Imagine when they have to memorize the map of a different keyboard.
