How about a $9.00 computer with 802.11b/g/n? Well here it is: Next Thing
Teaser: "The board is Open Hardware, runs a flavor of Debian Linux, and boasts a 1Ghz R8 ARM processor, 512MB of RAM, and 4GB of eMMC storage. It is more powerful than a Raspberry Pi B+ and equal to the BeagleBone Black in clock speed, RAM, and storage."

Watch out Pi boys/gals!!
Interesting stuff! I hope they calculated their price point well, because if I look at the Kickstarter page they will have to ship lots of them :)
P.S.: one of my Pi2s has, as expected, exceeded 400 RAC. I would think that this 9$ board could do close to 100 RAC (single core, but also NEON capable).
Received my Pi2 yesterday. Installed Ubuntu's Mate distro for the Pi. It is a port of Ubuntu 15 while retaining some familiar commands like "apt-get". It installed easily but the hassle was having to resize the /root partition to access all of the space available on the card. A little more involved then the "rasparian" distro which makes it easy through "raspi-config", a tools not available on Ubu's Mate. I like the look and feel better then rasparian.
My goal will be to attach this PI2 to a tracked crawler with camera so that I can thread CAT5 from the north side of the attic to the south side. My attic "crawling" days are long over especially when you factor in 130F heat. I have rolled fiberglass insulation rather then the loose stuff. I think the loose stuff would jam in the tracks and render the crawler useless. I am hoping this will not be a problem with the rolled stuff. In any event while it won't be the first of its kind with a Pi it will be my first time and should be "something to do"/fun.
This is my second pi. The first had a cooling fan with overclock heat syncs. I crunched with it until the fan bearings locked up. I bought a replacement fan and it ran for a while too but again the bearings failed. At that time I retired it. I also needed a plug to accomodate a "more mature cruncher" so the pi got a rest. That pi will probably become a "test Pi" for the crawler effort with hardware being transferred to the PI2 upon success. If the crawler is a success I might use it to prowel the pond with a mounted camera. I modified a shelf area in the pond and removed some stone causing it to be deep (2~3 inches)and flat. This created an ideal area for a natural bird bath. The birds seem quite happy in that they abandoned the standard bird bath for this new shelf area. There is soo much to do and so little time to get it all done. Stay tuned. I change my mind a lot.
Small fans are notorious for failling quickly. You'd be better off using an oversized fan at moderate rpm, which would consume about the same power as a smaller fan at higher rpm. The bigger fan would probably push more air, although the pressure and directionality of the smaller one is better. But cooling the few Ws of a Pi is easy with just any airflow.

Agree. I had looked into buying a 2" or 3" clear pvc pipe. Mounting the Pi in the pipe and attaching a 80mm fan to one end and a filter at the other end. This would definitely create a "wind tunnel" and assure adequate cooling. I am so impressed with the guys/gals who have the laser cutters for punching out Pi cases, but that is a bit pricey. After all the whole reason to have a Pi is to have an expensive computer. Hmm, maybe a 3d printer could make such a "tunnel". Now you might think this is childish but a fan that is illuminated by leds is a real plus. At night and somewhat during daylight hours a quick glance can let you know that it is turning. Stationary blades are not good. All of my big crunch cases came with illuminated fans but I used to turn the illumination off. Not anymore!!
I like the "pipe" idea, you could mount it vertically with the fan on top and give it a black finish so it looks like a shrunk Apple Mac Pro ;-).
I was at the "Maker Faire Hannover" last weekend and saw some "luxuary" ways of cooling Pis and similar boards:
E.g. a cut-from-one-piece-of-aluminum enclosure where the case sticks to the board with some adhesive thermal pad, so the whole case acts as a giant heat sink.
65 EUR or so for the case....oh well, but looks gorgeous.
And then this exhibit at the booth of rechenkraft.net e.V. [German]: A mini-cluster of liquid-cooled ARM boards. Also running Einstein@Home among other projects.

How about the Building Boinc for Einstein@Home and the Raspberry Pi 2 thread?

Very cool project. I found MJPEG-streamer (see here for installation hints: https://www.raspberrypi.org/forums/viewtopic.php?t=48597 ) very useful to stream live image stream from a raspberry pi camera to a browser.
Any plans what to do with the Pi once all cables are threaded?
