Fair enough, and your position makes sense to me. (A lot more sense than those who would specifically curtail software protections.) I think there's something to this approach, but I can't help wondering how anyone would define the lifespan of a product. Also, I think reasonable definitions would be much longer than you'd like and closer to the existing 20 years. I kept my last mobile phone for 6 years, for instance, so I'd probably say 10+ years is reasonable for technology in a mobile phone. WinXP is 15 years into its invention cycle, etc.
