There is always use for the floppy hole ... :beige:
I imagine a more permanent non-destructive installation in which case some kind of custom dock connector would be created. I could see splitting off the data lines to a mounted USB camera dock for plugging in cameras, flash cards and anything else the thing will support in the future (maybe even synching with iTunes.
Otherwise, put a small toaster mechanism in there for making Pop Tarts ... can't run any hotter than the original innards.
Or just a pocket for business cards, pen and stylus storage, and other "tools" you might use when docked. Maybe an Apple coaster for your beverage.
If using as a spanning monitor with your MacBook or desktop via the Air Display App, then the compact case can become a repository for hard drives and other peripherals, in which case the floppy port possibilities become endless, why you could even use it as a floppy port!
In fact the more I think about it, this solves the LCD in a compact case problem. Now you can just stick a Mini in the case, stick an iPad in the case and use Air Display to connect them. No hacking, no muss, no fuss.
Now I'm really jonesing to do this ... must wait until iPad 2 to pick up original one for cheap for this hack ...
