I think one's viewpoint in these things can be a function of age and years spent cycling. I'm not sure it always is, but I think it can be.
Generations older than I am wondered at the marvels of synchromesh on car gearboxes. They thought a single stab at the clutch was as a gift from heaven. Now that I've driven a few crashbox cars, I can see their point.
I thought synchro commonplace, but many of the early cars I drove lacked it on first, so no downchanges past second on the move. It still amazes me that younger drivers do this (and why they bother, but that's another story).
Similarly, I find five gears on a car more than enough, but younger drivers only get excited past six. I learned on four and back then only Alfas and Lancias had more. A few cars had O/D, but that was not a 'sporty' thing.
So... my 'fantastic' with bike gears as I got more into riding was a seven-speed cassette. Toe straps were pretty fly.
Now, in a world of Ergo shifters and clipless pedals and tyres that seem not to puncture, I'm in paradise. Really.
Someone for whom Ergo shifters and 8-speed cassettes were the starting point might want a little more of a tickle to get them excited.
This is where much of the initial market for future whizzbang stuff will be. There are those of us who know we will be just a fast on a ten-year-old 8-speed cassette with the shifters on the downtube.
And there are those of us who know that we were never really fast enough for these tweaks to have more than bragging-rights significance anyway.
Sadly, I am in the latter group.
