That is pretty cool, not gonna lie. Work in a reasonable sized mouse, good battery life, and an aluminum case and you've got yourself a deal.

Computer companies have no excuse for the lack of that feature.

Vibrating scalpels for home use would be pretty god damned awesome.

Forgive my ignorance, but what is the advantage of a vibrating scalpel over a normal one?

OK.
Just picture this.
Your standard iPod headphones that come with your crappy iProduct.
Now take away all the wires.
Tadaaaah.

Those things are ♥♥♥♥, the only redeeming thing is the little volume control on the wire.

iiiiiiiiiiiiiiiiii donnnnnnnnnnnnnnt caaaaaaaaaaaaaare lol
I just want something the size of those earbuds that are wireless.

A gravity gun.

Also they better be invisible to other people, lest you get caught when you ain't supposed to have them.

EXACTLY.

I want a Super Crate Box style disc gun.

You know, that's not a bad idea.
There might happen that one turns up in LPIndustries soonish :3

Gattling mini-nuke launcher (with a scope )

Anyone for some Less-Than-Lethals?

15 foot high bipedal mechs. Could be quite useful for rescue operations, heavy lifting and the occasional military use.
And by occasional I mean that a 15 feet armored frame could quite possible handle the recoil of a medium sized cannon/gau8.

Since it's not to big it could fit in tight streets and stuff, making it ideal for crowd control and it would scare away possible attackers.

Tl;dr 15 foot mech wielding a gau8.

Also keeping on with the whole wireless headphones- those would be great for athletes. I hate going out for a run and having to adjust my headphones if they slip or start to feel uncomfortable.
