Yep. Got a Gunnar crosshairs cyclocross bike. Use it for commuting in London, and out of town, about 70miles a week. The bike is acceptably light, and it has all the bosses etc: you could need. I use a rack (Acts like a rear mudguard and lets you dump stuff that is too big to go in a back pack on it) though mostly use a backpack, lots of lights, water bottle, on board pump. Tires are 38x700c which seems good enough for everything, dropping off curbs, running drain covers. Never used a MTB for commuting so don't know what it would be like. Can't see the point of bigger tires and suspension for commuting though unless you're commute included a lot of offroad.

PS rode this bike through central and south america mainly on non tarmac roads. Had 50lb on the rack. It coped fine.

I'm 183cm and 85Kg if that makes any difference.
