That would be a fixie. No, you do not want.
Anyway, how long is your commute?
The Schwinn looks decent, and it has all the accessories you need, and you can put them on the next bike you get if you grow out of it. The rear derailer is a mid-level SRAM, and should work fine if adjusted properly. Its not very stylish though.
If you want an upright riding position, do not get the Scattante. Look at the picture - the seat is 5" above the bars!
Have you test-ridden any of them? You should go to some local bike shops to test ride bikes, just to see how they fit and feel.
