23lbs? Seriously? Did you weight it? I owned a 2006 model one and didn't care much for it because of the weight. I'm pretty sure it was nowhere near 23lbs. It did feel like a nice solid bike though and for commuting only, I would have loved it, but I was looking for a do-everything bike and this one wasn't that good for rec riding with other roadies. Got dropped on the first hill and was dead tired by the end of 30 miles. Never had that problem on my road bike. As long as you like it, that's all that matters.
FWIW, I ended up with a Specialized Tricross Comp as my do-everything bike. Love it.
