Happy to review. Linux of course is free whereas Win costs £££ and this netbook is only used occasionally. Any ideas? Delete Zorin for Mint?
Instead of Mint consider Lubuntu or Xubuntu. They're based on the same original developers (Debian+Ubuntu) but are intended for low-resource systems. Which I'm afraid 1Gb RAM is nowadays. If you do go with Mint, which is what I currently use, do not pick Gnome or KDE as the window-manager. You might be OK with Mate, but all the stuff that Mint "helpfully" loads for you would drag performance down.
