What’s the best tablet for video calling grandma?

Chris needs a tablet or video-calling device for his grandma's Covid-19 isolation. What are the options?

I want to get my grandma a tablet for easy video calling. She is elderly and needs to self-isolate, and she is already quite isolated after the recent death of her husband. I am not sure which tablet or which program to use. She isn't very computer literate.

This new Facebook thing looks good but I am sceptical of the brand. Chris

Video calling used to be a futuristic topic. Today, it is readily available on most devices except, oddly enough, smart TVs. If anything, there's a plethora of services, and I haven't tried most of them. The options include Zoom, WhatsApp, Facebook, FaceTime, Google Hangouts, Microsoft Teams, Skype and many more. Zoom is a business service but it works well and is clearly flavour of the month, with downloads up by 1,270%. Fake backgrounds are one of its winning features.
