I've been using (and have written about) the iPole from FastCap, since I first picked it up at the Consumer Electronics Show in Las Vegas. The hiking iPole model or the telescoping mini iPole both offer a tripod mount (and optional iPhone case with tripod thread) is a great way to take self portraits and include yourself in videos. But the one downside is you have to stretch to turn on or off the recording mode.
I've used some apps that use audio to let you activate and deactivate that mode remotely, by clapping for example, but they can be unreliable in a noisy setting.
So I'm very excited about this new Bluetooth remote from Satechi. It does a lot more than just volume buttons (which acts as a record on/off switch with Apple's camera app, since iOS 5.0) and at $40, it's a nice add-on. There are numeric buttons and a button that acts as your circular home button, so you could activate Siri, remotely!
The rumor is that the Apple TV has a Bluetooth chip but it's not activated. If a future version of iOS or the Apple TV supports Bluetooth, this could be a nice remote.
I've ordered one of these remotes and will provide a hands-on review asap! If you're interested, try entering 10offall at checkout to save ten percent!
