Osu is really easy with a touch device (drawing tablet or tablet/phone/mp3 with touch screen). It's a PITA to do with a mouse sometimes. I think it's great practice for hand-eye coordination and accuracy with your mouse.
Talking about touch devices, I'm probably going to get one of Wacom's Bamboo tablets with multi-touch support to make Windows 8 more...fun or easier to use because it's tablet oriented.
Nah that's short story.
They are all owned by Chinese people, though. Only the really fancy Japanese restaurants have actual Japanese staff.
