Depends?
I guess it depends. iPhones: yes probably. Macs? Less certain. Monitors, peripheral? Probably not.
Besides none if that matters to the robbers if they can offload it, it'll be the people who buy it who'll find out the hard way. And it won't necessarily be sold off piecemeal in pubs, etc - they're closed at the moment. I'm not sure buying second hand items off eBay is going to be a good idea at the moment.
