I probably am in the market to replace them in that order. I just bought my son a Lenovo laptop because he needed Windows.
I'm dismayed at where Apple is going, so I'm considering a Dell Linux laptop as my daily driver.
I need to do some video editing, so for a while I'll use my son's laptop, and possibly get a Mac Mini if I really need to keep up with video editing.
My thinking is I'll buy the minimum I need to keep up with my video editing but make more aligned choices for my daily drivers.
Sitting on those thoughts more has left me entirely cold to the iPhone 12 announcements last week.
For video editing I was very surprised at how quickly I picked up / understood the Free version of Davinci Resolve after looking for a Final Cut replacement for my gaming PC.
There's an entire guide provided by BMD that tells you exactly what products are compatible with your OS and particular computer. It even comes as included documentation with the installer. You know, those PDFs in the folder with the install app that nobody looks at? After Apple's nixing Nvidia from their platform, you're limited to AMD GPUs for Mac. For PC, have more options. For Linux, you can go absolutely nuts with the amount of GPU since you can utilize some of the GPU appliances rather than PCIe boards.
