I have 9 speed MTBs and don't know why they went from 8 speed to 9 speed on MTB's. Seriously, when I upgraded the wheelset and seat post on the dually earlier this year, the last thing I was thinking of was changing the shifters and gears. I'd rather spend money on a new helmet.
With regard to road bikes, I started out on a 7 speed STI bike several years ago, rebuilt it as a 8 speed and did see a difference in the performance. Again when I moved to 9 speed, I was glad I made the move. When I moved to 10 speed it came with the new bike I bought. Honestly, I don't see much difference between the 10 and the 9 except the chains on the 10 wear out much faster.
