No your just insane. Plenty of people are still using 32 bit linux, and I'm sure plenty are still using it on 64-bit hardware even.
I don't even think most netbooks are fully 64 bit yet(I know my friends wasn't when he tried to install a 64bit version of windows on it, and it was just over a year old with an atom processor), which are all the rage if you pay attention to anything other than your big black rig.
Really, no one sane cares about 64 bits for what amounts to an accessory. Which is what skype pretty much is. Are you crying about your mouse not being usb 3.0? I doubt my keyboard is either, and it cost close to a hundred bucks. Hell, my monitors probably still worth more than my computer and 4 tb of storage attached to it, and it was made in 2004! Nice though, looks the same from a right angle as it does from the front. If I were to just leave a picture on it, it would look like a backlit painting, from whatever angle your at! Yes, it is a lcd and not a crt. I have upgraded some stuff in the past decade.
Of course my printer is the oldest of the bunch, it's a laser printer I got for 15 dollars. Nice just being able to print up 50 or 100 pages at a time just for the convenience of it, and not worry about the cost. The local computer store that still has plain VESA video cards on display(along with books on 2.0 linux based distros) in the back was shocked when I came looking for memory for it. I do have an inkjet for the fancy stuff, but I use it maybe once a year. Before anyone crys about the enviroment, yes I do recycle.
Yes I take it personally that people ignorantly assume everyone upgrades every two years for no real reason other than to run bloated software. Which is the great thing about linux, there's more distro's dedicated to being light weight than there are being filled with the latest eye candy. Then again, my old as dirt Pentium 4 is still well within the requirements of the most popular distros. Which should make it obvious that, most people using desktop linux are using it on older hardware.
