These days, I purchase laptops with a life expectancy of around 2-3 years. By then, the tech will have advanced to far that I'll want a new one anyway, and prices are dropping to the point where I can justify spending $1000-1500 on a device I use 10 hours or more a day, and for my primary source of income.
These days, if I wanted more RAM, I'd just buy a new machine.
