I used to ride a commuterised singlespeed MTB (still would if it hadnt been nicked!) but one fine day had a go on my friends fixed with 700c. I thought it was a bit jarring and unstable but within one ride I appreciated that the speed, lightness, and fun were quite a big improvement.
The solidity of the mTB was reassuring, and I didn't have to ride around as much stuff, but I have improved my bike handling (and speed) as a reslt of this change. For a 20 mile-a-day commute you could make your frame work, but as you know, the geometry and construction are not perfectly suited to doing the miles... Also, if you have a go on a 700c road bike, I think you will agree that having 2 different bikes is better than 2 similar but different ones!
