Following this (and by extension a lot of other folks):
* I don't own a cellphone. Work gives me one, but I never remember what the number is and I'm not sure I could check my voicemail. I find the interface annoying and confusing.
* I don't own any desktop computer that is newer than five years old. I have a five year old laptop that I never use. The last time I bought a new computer was in 1996. At the same time, I *do* buy embedded computers new: my Nokia N800, my Linksys router, (arguably) my wife's EEE laptop.
* My TV is from 1987. It was the baddest, ass-kickingest tube TV in 1987. Now, people make fun of me for it. The speakers on it don't work so well.
* I don't have a PVR. I tape things, and I fast forward through commercials. Because of the peculiarities of the TV schedules where I live, about 90% of what I watch on TV is Simpsons reruns.
* I don't own a functioning MP3 player. I have an iRiver whose interface is somewhat broken, and I don't use it.
* I can't program very well. This one is actually the hardest one for me to admit; I have a lot of shame over it. I can do some shell scripting and some Ruby but that's it. I have lots of colleagues I look up to whose programming skills range from middling to mind-blowing, and here I am with 13 years of Linux experience and I sometimes have to ask the dumbest questions.
* I don't play many modern games. Part of this is not having Windows or a modern gaming console (I do have a PS2 for which I buy the occasional very used game, and I am inching ever-so-slightly towards a Wii; Spore for Wii might push me over the edge). At the same time, I'm pretty fond of old NES/SNES/MAME/Genesis type games. The concept of paying a monthly fee to play World of Warcraft weirds me out.
* The oven in my apartment confounds me. You have to press one button to wake it up, and then set the temperature with buttons, and then another button to turn it on.. or do you? What's wrong with analog dials, dammit?
* I hate e-books. I really hate Amazon's Kindle; something I see as a very promising device that got wrecked by DRM. At the same time, I'm very fond of e-journals, at least those of which you can get articles in PDF format. E-books are (usually) just too laden with DRM for me to give a wet slap about. I will make an exception here for Creative Commons e-books.
