Having seen @thelinuxEXP's post on the @tuxedocomputers #InfinityBook Pro 14 Gen 10, I decided to take a look at their laptop lineup, and sure enough I find the InfinityBook Pro 15 Gen 10 with #AMD. In reviewing the specs, I've realized that this is perhaps the closest laptop to what I've been looking for this entire time.
To start, the InfinityBook Pro 15 is the only new 15 inch laptop I've actually been able to find. All the other ones I've found were either 14 inch or 16 inch. Second, this laptop is also the only one to feature an AMD Strix Point APU that's actually within my budget range that has removable RAM. Finally, it also has a 99 Wh battery, which is the largest of any laptop I've ever found. It also has other nice things, such as two M.2 slots for storage, a 2560x1600 300 Hz display, and an aluminum chassis. Honestly, it's really something I'd buy because, to me, it has nice specs.
The one thing that makes me uncertain on actually considering it, however, is simply because of the country I live in. While Tuxedo does ship to my country, our current government (read: circus) has been all over the place with tariffs (you probably now know where I live), and it may make this laptop unfortunately out of my budget I'm afraid. If I'm somehow wrong (and can avoid paying tariffs somehow), then this would be the top contender of getting a new laptop.
