By episode four of every new season of Doctor Who, I get sad about the season ending. It's a problem. Season 7 will probably be the same way. However, I recently discovered I can at least carry a Sonic Screwdriver around my house during Who hiatuses. Meet the Sonic Screwdriver remote.
This universal remote will allow you to control your TV or destroy fake Daleks. The possibilities are endless.
The product is available from ThinkGeek for $99.95, which is steep for a universal remote. However, the true genius behind this device is that it is gesture-based. For example, you can teach the Sonic Screwdriver to adjust the volume on your television with left and right turns, or open a Blu-Ray tray with a flick of the wrist.

On top of TVs and media players, the Sonic Screwdriver is compatible with many iPhone/iPod docks. Nearly any home media device can be connected to it.
In case you were worried it was made of cheap plastic, good news: it's made primarily of polished die cast metal and copper plating with some plastic gripping for your fingers. It takes 2 AAA batteries.

More of a Harry Potter fan? Check out The Wand Company's Wand remote. You won't be able to "Avada Kedavra" your least favorite housewife, but at least you'll be able to mute them. It's available on Amazon for $74.97.
Is your favorite football team already off to a bad start this season? Then these next two remotes might need to be part of your Sunday festivities. Brookstone's Clicker Bottle-Opening remote means a beer is always in hand while their Sofa Pillow Remote is perfect for those moments of frustration. Punt or change the channel, either way, the pillow is uniquely suited for both tasks. They are available for $12.99 and $29.99, respectively.

I'm patiently waiting for some really detailed reviews before I spend $100 on this. Come on, early adopters, get on it! And remember, it doesn't work on wood.
My boyfriend has the toy version (although this is a toy too?) that he got from the UK when his cousin was teaching over there. Well, two of them. One to play with and one to keep in the box as a "collectors item". This is hilarious and its going to be his birthday present. I hope he doesn't see it on the site.
@Niche - there's one that looks like the remote, but it's not a remote. It's just a toy one. This one is a remote control for the TV or other devices, not a toy.
Yes, I know there is a toy one. My boyfriend has two of them. I meant that this is essentially a toy too. You can't seriously expect this to replace a logitech harmony remote do you? It might work, it might even work well. I can even understand why you would want to wait for reviews. Why buy the $100 version when it doesn't even work? But does anyone really buy it because they really wanted a remote control or do fans want a toy that happens to be a remote control? I meant the comment in the brackets as a sarcastic remark but I think that probably failed.
It's not so much a toy as a conversation piece. I'd use it to impress sci-fi-oriented guests -- that is, if I had a hundred bucks to spare for a thing like this. I love the idea, though.
If the reviews are good...I might have an anniversary gift idea for the husband :) (and for me, who am I kidding?)
<whimper> want <whimper>
Makes me want more than one television for lots of geekremotes!
