A similar bike is the Bianchi
Milano. It's still an aluminum frame, but has a steel fork, which might be a little more forgiving. It also has 26" tires, which is neither positive nor negative, although they would make more sense if you are on the smaller side. As has been mentioned, the mustache bar of Jamis is a good thing, as it gives you more hand positions. The Bianchi looks like it has a flat bar, although it appears to have a little more sweep, which is good. And the Bianchi comes in their classic Celeste.
Although either bike would make a great commuter, you might want to find something used and inexpensive, to give it a go, before committing $500. My current commuter is an almost 30 year old Fuji Allegro. I paid $40, cleaned, lubed and adjusted all the bearings, replaced the bottom bracket, tires and tubes, and recabled the brakes and shifters. Admittedly, that is a lot of work, but perhaps a local bike shop might have a "gone over" trade in for short money. Might even ask if they would take it back for credit against a new bike, if purchased within 6 months.
