7 years is looong time to use the same machine. I can't imagine doing it. I'd probably use it for 3 years before replacing it. (FYI I bought my last laptop in October '12). I'm not so sure if it's that incredible. The battery life is definitely incredible. But the screen is just 1440x900. Also, what about performance? It seems like it offers just average performance (a necessary compromise for such long battery life)...
