Riding good. Always. Why wait for summer?
But - since the ideal number of bikes in N+1 AND we have here a near perfect excuse for the +1 ... then here is opportunity knocking at your door. Buy something that works for your commute but is as different from the Allez as possible! Expand your horizons (that's what school is for , no?) and get an alternative ride that interests you, suits the need of the commute, and which would not create hardship if stolen.
Good to strike a balance between a nice patina of age and non-descipt-ness so as not to attract attention with a cool retro hipster vibe and maybe a rack and baskets both to declare your green-ness and increase utility. No need to deck it with plastic sunflowers though, IM(H)O.
Plus - you then have a spare bike for casual rides when someone from out of town comes to visit. As long as you are skilled enough to ride the Allez slow ...
