The reason achievements are more popular is the same reason that trading cards are more popular then stickers. It is all about building a collection, and some developers take the time to create unique titles, or even more interesting point rewards for some of them. Ironically I think the rarest achievement I have is from Blue Dragon, and it required me to run from battle fifty times. It wasn't hard to get, but it was strangely enough pointless to get. This particular achievement was worth zero points. To a lot of people that means it wasn't worth the time.
That however makes it a truly rare achievement today. Long after the game has left the retail channel, and since almost nobody who played the game cared enough to get a shaming achievement. I have a bragging right that a lot of gamers with more points then me don't have. I can say I got a zero gamer score achievement, and if you don't believe me you can go compare games for yourself.
Personally I hope Microsoft takes the concept further. I would love to be able to arrange my achievements for display, and it would be even cooler is unlocking a achievement also unlocked a trading card for the game in question. Add just a little wheeling and dealing into the mix.
