Chromebooks
Since (a) I am fed up with installing. maintaining, keeping virus-free and updating my OS and general software, and (b) most of what I do is on-line work, and (c) free wifi is available just about everywhere in London and here in Spain, I purchased an Aesus Chromebook, the larger screen version.
The only additional apps (it comes with a lot) I have installed are those enabling off-line work and WhatsApp.
All my settings (including AdBlocker) were already on my Google account.
A truly excellent device. Anyone thinking of purchasing one, PM me for a discussion.
