Computer monitors are another example... they keep getting bigger and better as the prices get lower and lower. Eight years ago the standard was a 14" or 15" CRT (the old style of monitors that were typically deeper than they were wide). A 17" would cost you $250+. Today I got an email listing a 25" flatscreen LCD monitor for $220! It just blows me away.
Also on an anecdotal note... this reminded me of a fad that I recall taking place in the early to mid-90s (I personally knew at least 4 guys who had done this) where people with finished basements would set up a computer desk next to an inside wall (usually the inside wall connected to a utility room of some sort) and cut a hole in the drywall through which the vast bulk of their CRT monitor would go. This created the illusion of a flat screen monitor. which at that time in history only existed in Star Trek and other Sci-fi movies or TV shows. Only a few short years later, voila, we have 25" flat screen LCDs for $220!! What a world we live in.
