How about this new Raspberry-pi Linux computer for $25 or $35 coupled with a sensor board ?
Has a header on board, video 256k memory hdi video or composit usc sdcard.......
see here for all specs.. http://wiki.xbmc.org/index.php?title=Raspberry_Pi

I have one on order. It's the cheapest and most low-power way of getting a real PC up in the air, and the power draw shouldn't be more than a watt or two. This first batch was limited since it's a non-profit foundation, and the first production run was funded by the backers mortgaging their homes. From now on the new batches will follow demand, so give it some time and they'll be in stock for anybody wanting one to easily buy one. Removing unnecessary connectors should be easy and the GPIO pins on board can be used any way you want.
Might make a decent field ground station
It eats your battery alive!
@Ellison, I think you are being to negative. They have 2 big distributors (Farnell and RS Components) which take care of enough stock. The initial plan was to have batches of 10K RPi's each, but the Raspberry Pi organisation has mentioned that supply will be on demand.
Furthermore, it's waaaay more powerful than any other $25/35 board currently available. If your plane can handle the extra weight, I see no problem. To interface with sensors, gps, etc... an Arduino can be used through the I/O pins.
its got i2c spi and others
It's the law of supply/demand. The demand is always going to be higher than supply at the price that it's being offered. Their margins are too low to really keep any amount of stock to buffer the demand. That's just the economics of it. If they open source the design, then the Chinese clones can come out, then we're talking a different scenario.
It may be 40g, but could be lighter. I bet most of the weight other than the PCB, is in the connectors, which are not needed, anyways.
It only weighs 40g

Mine is being shipped...

Suffers from perpetual out-of-stockitis, and it's got so many heavy connectors on it.
