I’m not sure if the legal / warranty situation is the same here… I’ll have to check.
Also, although I much prefer being hands-on, I live in an area that’s not very big (~130k metro area at most). We have a Best Buy, the usual discount / department outlets and that’s about it. There are a few independent local computer companies ($$$$) but to find anything else it’s a 100+ mile drive. That’s certainly doable for some things, for example, I bought my truck from a deal 100 miles away. But the attractiveness of going that relatively far repeatedly kinds of diminishes with smaller purchases. But a good idea nonetheless.
On the topic of the Lenovo one neat feature I just read about is, it comes with a pen. When used on the laptop the (reasonably large) trackpad functions as a graphics tablet instead of a touchpad. Nice feature for mobile photo editing, even though I have a dedicated Wacom tablet for desktop use with an external monitor and keyboard.
I agree, on Windows you need 32GB instead of 16GB for your needs.
But in my opinion RAM is not the bottleneck for photo editing when you choose a iGPU and 32GB RAM.
Plus, the integrated iGPU inside a modern Ryzen AI 7 (the Radeon 860M) is 3 to 4 times faster than what you have now, and it runs on memory that is much faster too.
Check the specs for Memory speed (DDR): 7,500 MT/s. There are also laptops with a Ryzen AI 7 processor that have 5,600 MT/s or 6,400 MT/s RAM.
For 4k video editing or 3d rendering you need dedicated graphics card.
