• Beatmania controller: stub + dull wording
• Dance pad
• Drum controller
• Graphics tablet
• Keyboard: stub + extremely short
• Mouse: stub + almost solely about mouse-related osu! options, which is odd
• Touch device
• Wiimote -- do we need it? looks like it only exists because of mention in osu! options
• index page

i'm not sure we need stubs for all of these, i mean they're not osu terms or anything. wouldn't one article be better?

for exotic devices, sure, but I imagine that for keyboards, mice, and tablets it's possible to produce something decent that would pass as a separate piece of text
