...this is my last bike and I'm keeping it forever if I can....
+1 on the sentiment (I can't promise to never get another though
)
But I'm happy with the 2013 I got. In fact, if I knew then what I know now, a 2011 or 2012 could have saved me some money for the same bike. (albeit a different colour perhaps)
New features are nice and all, but you'll be perpetually unhappy if you constantly "pine" for the latest/greatest thing.
You see the same thing in other markets - cameras, phones, TV's... Is a new TV going to make viewing that much better? After 10 or 12 megapixels, how much can be improved by adding a couple more? There are exceptions, but I'll bet they're few and far between...
This is all IMHO, FWIW, and YMMV and all that...
