In reply to Y Gribin:
Quite a bit has changed since 2010. Some of that will just be change for no good reason but some significant progress has been made. Clutch derailleurs, for example, are an awesome step forward and I don't think you'd be able to put one on an old 9-speed bike.
I don't really keep up with bike prices but my instinct is that the price is a bit steep for a 2010 hardtail, even a nice one that's still in good condition. I suspect used is still the way to go at that price point, but I'd look for a better deal.
