Index gearing and the like is soooo over rated for your bread and butter bike. You'll spend more time tuning it every week than riding!
every week? you must have had some rubbish index gears if that's the case. Probably didn't spend enough on them :-)
Even with racing I'd be looking at my shifter adjustment every couple of months at most. Once a Bowden cable has done its initial stretching (first couple of weeks) then it's fairly static right up until the point it frays and breaks (which could be years). Adjustment is made with a small knurled knob in exactly the same way you adjust your clutch cable.
The bits that wear are the big lumpy mechanical bits: chain, sprocket, derrailleurs. That's true of whatever brand or level you fit.
Steve has a point, if a bike is nice to ride, you will ride it. Why make what is already a strenous exercise any more unpleasant?
My mention of Shimano hierachy labels is easy to explain. Anything below LX is for sunday riders and not robust enough for hard or prolonged use (IMHO). XT is better made and lighter than LX, but more expensive. The performance is fantastic though. XTR is full-on pro level, very light, very nice, but not worth the money for commuting or leisure riding. Given those parameters I'd say that my choice of LX was sensible. Anything less fails in hard use and that's just annoying and a waste of money.
Your bike was right for your commute and your mindset, but if your philosophy was foisted onto a casual or less committed rider then they would become disenchanted with cycling very quickly. I know, I used to sell bikes to people who would tell me what they needed and then buy an unsuitable bike on cost grounds. then they would return and say they weren't enjoying it or the bike was broken or it was too expensive to run. Horses for courses and all that.
I don't see anyone telling us that we are daft to ride large capacity singles when a Honda C90 is fine for the job. Why bother with that fancy clutch when you could have a marvellous semi-automatic change? Why keep replacing those trendy fork seals when you could have the tried and trusted C90 fork? Why get cold legs when you could have the best in plastic leg shields... and all for loads less than your trendy complicated motorcycle :-)
Mind you, I knew I was going to far with cycles when I bought titanium chain ring bolts for about £35!... that pulled me back from the brink. But that's racing for you, you keep looking for an edge.
