Linux video: not a problem
Linux sound: not a problem
Linux printing: not a problem, though I understand it's printer-dependant (I like Brother)
Linux iPod: dunno... I bought a reasonably priced mp3/ogg player and it works great.
The bit about ice cream was what we call in English a "joke".
I do, however, wonder how you can be so certain that things like video and sound will work on their current hardware without having the faintest idea what that hardware is. Is this omniscience common in the Linux world?
