This is something only the nerds complain about. The general public prefer Bluetooth buds. If there was significant demand for phones with AUX, someone would build them.
This sort of thing has always been standard practice in the automotive industry. The point is, this won't work to paper over the cracks in China with their massive oversupply.
The Chinese EV industry is overdue for consolidation. There are too many players chasing too few customers. This could be done in a relatively orderly fashion that leaves a few big players that are internationally competitive. Or they can keep kicking the can down the road and hope for the best, until the inevitable collapse. Gee, I wonder which option they'll choose.
It took me over a year too. I was using a mini PC with Mint but still kept my old Windows PC under my desk. When I built a new PC, it never got defiled, though.
Take it slow. Install a VM with Mint. Play around with it. Get familiar. Move your regular usage over to it gradually. Make the jump when you are ready. It's perfectly OK to have reservations about a big change like that. But you don't have to do it all in one go.
When I went on a trip in the early 2000s, I took a phone, a satnav, an MP3 player, a camera and for longer trips a netbook with a UMTS stick (3G modem you could plug into a USB port). Plus all the associated chargers, cables and other gubbins. I felt really cool and modern with my huge, clunky tech bag. Now that seems quaint and outdated. I wonder if people will feel the same about smartphones in 20 years.
