I like the new commuter bikes. I've been riding the same kind of bike for years, albeit mine is thrown together from old parts, including IGH.
It's nice to see that the bike makers are able to make a decent bike that's suited for regular urban transportation. They tend to have a comfortable geometry and fittings that you would otherwise have to pay extra for such as fenders, rack, etc.
The problems are not specific to commuter bikes, but affect all styles: Low end bikes have compromised components such as steel parts that will rust if the bike is used outdoors in varying weather. High end bikes are expensive and call attention to themselves.
Some of the things I don't like, have to do with marketing:
* Treating "urban" riding as if the city is some kind of treacherous jungle, to be conquered. Gimme a break.
* Bikes that look too much like they are designed for 60-somethings riding to the "farmers" market on Saturday.
