1) Actually, chances are anybody who's ever browsed the web has used Open Source. Ever heard of LAMP? Basically, 90% of websites run on the LAMP stack. The 2nd most popular browser on the market (Firefox) is Open Source. Yeah, nobody uses open source
2) We're talking about a mobile computer that can be used to help a person manage and enhance their life. Considering how much computers are penetrating our day to day living, restricting our freedoms with the devices that we paid hundreds for can be very inconvenient.
3) What's so douchy about wanting to access your PBX via a more secure protocol, or having any other functionality that would appeal to a geek or an enterprise user? The beauty of the Android market
S lies in the fact that there are packages for both the regular Joe and the real geek. Better than 99% of your platform's packages being useless stuff just delivering advertisement for various businesses. Download the Geico "app" and the Fat Bastard Burrito "app," while you're at it.
No self-respecting fatass anarchist would go anywhere near Ubuntu, whose unofficial motto is "like Windows, but it works." It's easy to install, easy to use, has a lot of eye candy and lots of packages preinstalled, but that also means lots of bloat. Not a bad thing, and I use it for my desktop system (everything works out of the box, it's stupid-easy to install packages, has great built-in hardware support, real no-brainer), but I wouldn't run a server or be involved in any clandestine activities on that platform.
A lazy fatass anarchist would probably go with Arch, while a real fanatic would probably just do LFS (Linux From Scratch). I might go through the pain of doing LFS just to learn about the internals, which you typically wouldn't using Ubuntu, which serves everything up on a silver platter.
