first of all I think we have become too much of a "disposable society". while I am sure every intends to own there new 2009 trek madonne til death or theft do they part, as soon as the slightest hint that a specialized Sworks bike is better (and won 1st and 2nd in the TDF), the madone becomes junk and specialized is the king.
2 I think bikes are too homogenized these days. there are not enough differences to really make on stnad out from the other. Oh sure there is very little difference between a 68 Clubman and 69 Clubman but there difference that you can see and feel. the only difference between a '09 Bianchi Infinito Ultegra and '10 Infinit 105 is the color.
I think 20yrs from now the bikes we are scrambling after will still be the sought out classics.
