I have ridden my CX bike like crazy since getting it in April. Commute, and lots of road riding time. Now it's CX season, so the bumpy tires are back on and it is dirty dirty dirty. It gets to have road wheels back on it Saturday and Sunday, then back on the CX track Tuesday. It has been a great all-round bike.
I did put a better cassette on it - the gearing is a bit high for climbing, but low for speed (46/36 on the front). So I put an 11/28 cassette on and it has served well for centuries, hill riding, and my own personal TT route I do at lunch (takes a while, I can only do about 18 something).
