Agree with tsl and blackhawk but add...

Yes, any bike will do but it depends on the commute. Commutes can vary with distance and terrain. Many of mine are within half a mile so any of my vintage middleweights are perfect. They're comfortable, easy to hop on, easy to hop a curb, tough, fendered if needed, etc. At more than a mile or so an English 3-speed is a great choice - it's lighter, faster, has those extra gears and still fairly comfortable. For the 10-miler commutes my MTB with 1.9s is great - faster yet, can hop curbs or plow through gravel/grass. For commutes to the next city - the road bike. There are plusses and negatives with each choice - with a speedier, more efficient bike you sacrifice a little comfort.

Now for those who defend a road bike for comfort I'm in agreement to a point. A road bike during a hundred-miler will ultimately be more comfortable than an MTB, hybrid, etc., especially with respect to the time savings/speed but I wouldn't choose to ride it down it down the block to the convenience store.

Now for old heavy ballooner bikes, ug! I'll use them only for show - or a Tour de Fat parade.
