To be fair, nobody actually NEEDS to deal with this nonsense. Windows works just fine without an activated key, literally the only downside is the "Please activate Windows" bug on your desktop. That's it, everything else works fine.
They cost like $5 online, it's not like it's a huge risk. I've bought OEM keys before and they work fine. Just use a credit card so you can easily get a refund if it's fake.
Then please, buy the Beelink thing so I can get a Pi 5 for projects. I already have chargers, plenty of SD cards, a 3D printer for an enclosure, and a box of 50 heat sinks of various sizes. And I'll be just fine with the base $60 model, so that's all I need to spend.
I just started using it an hour ago and I already paid the $3.50 for ad free (one time purchase, by the way) and I'm uninstalling all other apps I was trying. Liftoff, Jerboa, Thunder, Connect.... All dead to me. 😆
That waterproof/durability argument doesn't really hold up. We had waterproof, durable Android phones with user replaceable batteries a decade ago. They were made primarily of plastic, and had a nice thick gasket around the battery cover.
That's part of the problem with all these phones made of "premium" materials like glass and titanium. They serve no functional purpose, they only make the phone more expensive and less repairable. And of course, both of those things are great for manufacturers that want to sell you a new phone when you drop it ONE time and the glass front and back crack.
Back when I had a plastic phone I didn't even use a case, I beat the hell out of it and it never broke, and I replaced the battery myself in thirty seconds.
It's completely unnecessary and I love it
