If you like it, don't replace it. I have a 94 Hard Rock and i'm finally getting a new Hard Rock. In my case I've just wanted to have a lighter aluminum frame. For 17 years it's been good and it will still work for years to come. When a bike is advertised as lifetime guarantee on frame, utilize it--you paid for it. The next bike I get, hopefully, not until 10 or more years from now, will probably be a 29er with disc brakes. Not everyone gets the cash to update all the time, but the advantage to waiting longer is you'll have better technology. Tell the shop your waiting for better technology(how about a triple shock system) and that nothings impressed you in recent years.
