The ipod? Why? Why not just put "portable mp3 players"? It's not like the ipod was the first or is the best. Just the most popular.
and WoW... it's a MMORPG, there were others before it and there have been much better ones since. Again, good popularity, not much originality or quality (this ones pretty subjective however.
Facebook? Someone using HTML and Flash to create (yet another) website where ppl can be self-centered, narcissistic, obsessive, and share more information about themselves and their personal lives than any sane person would care to hear... THAT'S "technology"?! WTF. It's a USE of previously-existing technology, a stupid one at that.
I thought this might be a list of technological advancements that drastically changed our every-day lives and made significant steps to bettering them (the Tivo sorta fits the bill, but again, a bit too brand-specific, "digital media recording/distribution" would have included Tivos, and all the similar devices, as well as hulu, netflix, steam, etc)... but this is just a list of things that the mindless, corporate-controlled commercial masses have latched onto over the past 10 years.
Fads =/= good (let alone best) technology.
