Does anyone have information on doing something like this wirelessly? Provided your sensor has its own power source, couldn't you use the fm receiver built into a lot of phones to receive data from an external sensor?

That's what I was afraid of. In the quantities we're looking at, maybe we'd be better off jailbreaking and selling the whole thing as a package. Or maybe I'll just drag my feet a bit and hope there's a decent Android tablet with USB host and an SD slot coming soon...
You should take a look at Adam from Notion Ink. It's USB host. To me that's the killer feature, for this reason!
So far, it's vapourware. That's something I just can't get over when I consider ordering one.

If it's vapourware then what were they showing at CES 2011?

#34Maaaaan I had this idea over 2 years ago... except my ideas revolved more around robotics. I wish I was a bit older so I had the resources (money) and time to work on these kinds of ideas that I have. Previously, all my time was consumed by school/internship/band (I was a signed, professional touring musician). And now all my time is consumed by getting my startup going... in the hopes that it will eventually be somewhat self-sustaining enough to cover my living costs while giving me time to pursue these other more interesting ideas. Sigh... sorry for the rant that I'm sure no one cares to read.

#35Now if only you were permitted to write software to take advantage of the cool hardware you build.
There is a guy who has about a dozen of apps in the store that (ab)use the headphone jack to power and control external hardware.
Among them is a laser pointer [1], a controller for RC power outlets [2] and countless others.

It's vapourware until you can buy one. A lot of things that are shown at CES do end up being cancelled before they're ever released.

#37Wow, that's a hell of a hack just because your smartphone maker wants to rent-seek your serial port.

The pre-orders are shipping. Mine will arrive in about two weeks.

#39Also check out the Southern Stars SkyWire. Apparently it's a true RS-232 I/O cable that plugs into the dock connector. They use it to drive telescopes, but apparently it's not limited to that. http://www.southernstars.com/products/skywire/index.html I've gotten as far as opening an input and output stream with it, but I haven't had time to dig up an RS-232 device to try talking back and forth.
Unless you have a jailbroken device, arbitrary apps you write won't be able to access that stream.
You can use the EAAccessory framework to talk to it. Just use the protocol string "com.southernstars.sw9a".
What I'm not sure of is what sorts of apps they'll let into the app store that repurpose the cable.
EDIT: Here's my test code thus far:
