If something can be done on the PC/iPhone/iPad why not just use @Cloud? Besides, I am sure many of us have so many things to do that we have enough things to do for each of these segments. Just set the typing task for your PC, the easy-to-do-task-on-the-iphone for the iphone and so on.
By the way wksims86, if you are studying law may I recommend use of a spaced repetition program called Anki? I know someone studying for the bar who uses it and you can set the percentage of the material you want to remember and it works very well.
