My sister and I have arrived at a joint conclusion that the longest any laptop irrespective of its price can be expected to function without turning into a constant source of aggravation to its owner is about three years. After that period of time elapses, you can either dedicate your life to struggling with the laptop, or just forget it and buy a new one.
So the solution for those of us who do not have very sophisticated home computer needs is to buy an inexpensive laptop every three years or so. If all you need to do is use the Internet, edit texts, create PP presentations and Excel sheets, and play an occasional game, there are perfectly good laptops out there costing between $300 and $500. Buying an expensive machine for $2000 doesn't seem to prevent one from being driven nuts by it in three years, so why spend all that money on it?
