I don't code, game or do anything more resource intensive than watching videos online. Otherwise it's email, desktop publishing, Photoshop, Office, Telegram, Zoom (when I get it installed).
A friend told me before I bought the laptop that 4Gb RAM would be more than enough for Xubuntu. Have an opportunity to get 12 more Gb from eBay Seller for half price ($60). I suppose I could get 4 or 8 Gb more instead for a discount as well - I saw that someone here had installed 16 but only had 12 Gb available. Haven't installed RAM for 25-30 years. Don't relish it.
