Just use KDE connect (it's also available on windows). Just open your file browser and select the last screenshot on your phone. (It mount your phone as removable media)
It's all local and you don't have to send any extra info to Microsoft as added bonus.
All this new and fancy stuff is already solved on Linux for a long time and on windows long before Microsoft "invented" it. By great free and open source projects.
I upgraded my girlfriends PC grom a i7-4770 too a Ryzen 2600 and just moved the drive without any problems.
I don't needed to update or change anything. Only needed to select the drive in the bios.
AMD is better on Linux most of the time. Running a AMD card day one is not hassle free.
That being said if you pick a up to date distro all 7000 and 6000 series should work fine now. They are already in the kernel and mesa for a while. You may want to update you kernel and mesa sometimes to get better performance and stability.
But in my experience nvidia is fine on Linux. (I only used older cards gtx 970 and a rtx 2060) especially when you have just one monitor or all monitors on the same refresh rate. It's not on par with windows but will work with the Nvidia drivers.
So I would say if you a simple setup Nvidia is fine and AMD is better. It all depends on the best deal you can get. If ray tracing is not that important AMD is new the best value. If you more on a budget second AMD Rx 5700 XT are pretty cheap here and there are some good deals on Nvidia 30 series cards.
As far I have read intel cards can be a pain on Linux. So I would not recommend it for now.
Maybe a watch supported by asteroid os is something.
Some models have support for heart monitor. Don't know if there is a fitness app or something like that.
I live in the Netherlands and now pay €188 a year. It's just a "wa" insurance meaning if I hit something they pay the damage of the other's, but not mine damage.
I drive a car from 2009 and have 10 years of no damages. So if your willing to move to the Netherlands wait 10 years you can lower your payment. (Not really a option I guess)
