There are all sorts of possibilities. For one running Homebrew in Wii mode including being able to take advantage of the wireless networking, USB ports, etc...
Imagine a XBMC style application that uses wireless ...
indeed, think of the people using flamethrowers to do the 5 wire install and imagine them doing a 48 wire (did not count) install
... and the fun you will have to repair one million damaged traces...

i hope that they discover some other way to change data on the flash, perhaps via sd-card or dvd card, because I for one would never try an install like that.
