After all those new extensions introduced over the last decade, you bet my life has changed a lot since then
End users have hardly noticed...
Like most anything, there is a classic "S" curve pattern that needs to arise and you are pointing that fact out.
In the start of a change, there are very few adapters (those are the few that stand to make the most when the wave hits but we are not going to discuss that at the moment).
Only a handful (in this case, extensions and users) make the appearance. As time progresses, you see that there are more people jumping on the bandwagon until yo hit a point where things go parabolic (nearly straight up), at that point in time you ride it up until you reach "critical mass" and then it starts to level out.
They call that the classic S curve.
You will find it to be true in almost all facets of life.
The telephone. It went from nearly no adapters in the beginning, to more and more jumping on the band wagon, to parabolic to critical mass to the point that nearly every household (at one time) had a lan line.
Same with cars, computers, cell phones, CDs, DVDs, MP3, TVs, websites,... anything technology driven all fall into this S curve.
Granted the change is slow right now. Hell, this may only be the beginning stages and it may end up something completely different that we wont recognize at the moment.
But in the end, all things do change. Websites (to include .COM) where slow to take off in the beginning. Some businesses did not see the value of an online presence. Those that did (the early adapters) stood to make the most. Then you had the band wagon, then things went parabolic and now if you have a business, you have to have an online presence.
Its just the way things roll.
