An old Toshiba Satellite.
LOL... you could do with an update. Keep an eye out starting now. No one will be want to be stuck with “old stock” and expect 11 on or around Oct. 20
Install Linux Mint on the old satellite to breathe lots of new life into it when you have upgraded. Be careful though. Once you have seen just how well Mint runs and how easy the transition is for a windows user, you might just upgrade your new Laptop to it as well.
Antivirus... Linux dont need no steenking antivirus.
