I can't speak to 3 years, but all those tubes make for one SOLID bike. It's like a truss frame. You are riding on a small section of suspension bridge.
And the 2.4" tires roll way more easily than I thought. What are you waiting for? These things are getting very hard to find I hear. Oh, they aren't $500 anymore. I paid $750 USD a year ago. An absolute bargain. If there is a better bike value going I want to see it.
