So, could users just ignore that and just buy an anti-virus product or use 0patch? If it's like Widows 8, most apps will still be updated for a few years.
As a heavy user of Playit Live, Excel with macros and Google Drive, I'm stuck in a Windows World for a while yet. The first two could maybe run in Boxes if I send the audio to a USB device.
The most important thing to get updates in the browser tbh. That's the source of nearly everything bad these days, and the main reason somebody would bother to update their PC.
I reckon they'll continue providing updates for those for as long as there's enough people using it. It's not like Google are going to willing turn round and go "whelp, no more adverts and spying for these millions of users!"
