The problem today is OVERCHOICE. Read https://en.wikipedia.org/wiki/Overchoice

"The phenomenon of overchoice occurs when many equivalent choices are available."

With laptops you have a price range from just over 100USD to thousands with hundreds if not thousands of models available. This is overchoice at its finest.

Here I know this so I can shortlist the features I want then make a short list of 2 or 3 and then go shopping. If I continue finding more in that set I would risk overanalysis and never deciding.
