Labcoat for the workshop, made by Trish at Thunderbird Design. Attractive, functional and personal.
Millie (in the Grandmother series - despite being named after an aunt) is an Asus VivoBook E402SA laptop computer. I am not happy with this machine. It runs Linux Mint, but spends too much time freezing. It will be replaced.
Martha (in the Grandmothers series) is an Asus VivoMini VC-65 desktop machine running Linux Mint. She replaces Arthur. This will probably be the last device with a DVD-writer.
Molly (in the Grandmother series - despite being named after an aunt) is a Huawei lite in Sapphire Blue. Used as a personal device.
Ariadne (Oliver) is a 13" MacBook Pro, currently awaiting an upgrade, and out of service. In all likelihood the last device to be named after an Agatha Christie character.
