I never upgrade anything. Every lap top I've ever had only last 4, maybe 5 years. I would suspect that in 2 years or fewer, this machine will be dead and I'll be stuck with some new M/S O/S that won't be compatible with much of my present software. I really wish MicroSoft had some real competition with an operating system that would be good for 5 years. I'll never figure out why they had to leave XP-Pro which was ROCK SOLID. Win7 isn't bad but not as good as XP.
