The bikes in the links you provided are fixed-gear bikes. They are designed for track racing, but some people ride them on the road. They have no brakes, because the idea is you can use your legs to stop, though this ignores the fact that most braking power comes from the front wheel. They do not coast; your legs are moving every time the bike is moving. They have only one gear. They often do not have the mounting points to attach racks and fenders. If your commute is on flat ground, it never rains where you live, you don't need to carry much stuff, you have strong legs, and you don't expect pedestrians or motorists to do dumb things that require you to stop suddenly, a fixed gear bike might be worth considering.

If your commute involves hills, if you like to be able to coast, if you like having reliable stopping power, it rains, and you need to carry stuff on the bike--in other words, if you are like 99.44% of bicycle commuters--you should consider a very different kind of bike for commuting. I personally am a big fan of the Breezer Town Bikes; I commute to work on an Uptown 8. The Breezer bikes give you an upright position so you can see traffic; they have internally geared hubs so that you get the advantages of multiple gears without having to deal with adjusting derailleurs; they come equipped with racks, fenders, a kickstand, and other useful accessories; and they have good brakes.

Other manufacturers make similar bikes, and a good bike shop could build one the way you want. Again, though, don't buy a fixed gear bike for commuting unless you know what you are doing and you are willing to accept the tradeoffs. It's not for beginners.
