Strongly disagree. This would likely be a step backwards technologically, particularly in a cafe. The whole point is to make devices more portable (ie foldable phones). Why would a cafe put a bunch of monitors in their space when they can simply provide Wi-Fi? No one wants a dumb terminal, they want a devices you take yourself which belong to you. Laptops, Tablets, iPhones. This would be a huge step backwards.
Yeah, while the functionality is nice, it’s still not a replacement for a full computer. People with any sort of portability needs will not give up having a full laptop for this, as you’d need to have a separate monitor, keyboard and mouse wherever you went. Are you going to ask your clients to have a monitor/keyboard/mouse set up for you when you arrive for your meeting? So unless you have a designated workspace with this require equipment always available, I don’t see the use case.
