I'm starting to think I need a real road bike with cycling shorts.
Go for it. Especially a decent cycling shoe and cleats and pedals make a whole load of difference, the rigid frame is just a pleasure, and a modern group set allows shifts so smooth...
Plus, when you put on the spandex, you've got no excuse to go slow
There is a certain cost involved though, even for entry-level gear... A two-year used alu/composite road bike from ebay/some cycling forum is the big scary lump, but then the helmet, glasses, gloves, shoes, shorts, tops, socks, leggings, arm covers, wind breaker and other assorted accessories quickly add around 500 dollars/euros/pounds. On the other hand, some people benefit from some financial commitment, to actually get off their ass and ride for their monies worth

Maintenance is relatively bearable, new set of tires every 1-3 years, new tubes every year, new grip band every year, new cleats every year, and around a derailleur hanger every 1-2 years or so, depending on how often the bike falls. Rewire is probably best done after 2-4 years as well. Brake pads should be good for the same period. After 5-8 years you're looking at replacing the group and wheels, so at that point changing bikes usually is a better choice, while selling your old frame set to someone in need for some change.
On another note, I am quite surprised that there's no bike-tech thread in the "garage"
