I was going to say something along the lines of "you don't NEED something that large, blah blah blah" but I realized it was in bad taste. Sorry. Bad examples.
The webserver thing was a bad example, but the PC one does kind of bug me. At my last job, I had people coming in to customize $3000-4000 dollar computers with dual core processors and huge graphic card upgrades who were using their computer simply for day-to-day home computing. Spending that much money for a machine you'll never really use is pretty pointless. I do my music rendering/processing on a 1.3 ghz p3 with less than a gig of ram and an onboard sound card. This is more than most people really need, since the average computer user doesn't do much more than word processing and checking their email accounts. Consider this a clarification of my previous post.
And, I-baLL, the topic is your pet peeves, so if conspicuous consumption is my pet peeve, so be it. Sorry I miscalculated on an example, but you can fuck right off if you think I feel that way to try to be cool.
