A storage-less Camcorder, as the main issue when buying a camcorder right now is choosing what kind of storage medium is it going to have, CD, DVD, those little tapes, solid state or a mini hard drive, but it all goes to your computer in the end so why not just have a wifi-card instead. Then you could record all you wanted within range of a wifi receiver and then that could forward the video steam to a computer that is setup to record the stream. And that computer could be anywhere in the world.
Hay how about a digital camera that when in the range of a compatible wifi area gives you the green light to upload your photos to a remote system and clear its local memory. That way you could take as many high res pictures as you wanted.
Sorry about this, but Microsoft Research gives me ideas.
