Jay, you are complaining that to view posts, your system is slow. And that you are saying that other posters posting graphs, timeline charts, etc. is slowly the site down....which is not true. The site is not going to limit posters - just because you don't like the timeline posts that others, like me post, and that you don't have the skill nor inclination to make.
Instead of being resentful to the advice others posters are making to help resolve your issues - you should be thankful, and say thanks for the information.
As far as a replacement for your laptop, take a look at the AWOW Mini PC desktop computer, Intel Cleron N3450, Windows 10, on Amazon. They are small and are very affordable, around $130 U.S.
