I think all my laptops ( bar one) and PCs would run Win10
If there were drivers. Probably some don't have drivers. Graphics likely a big issue. Also PC Card SCSI adaptor for scanner would need replaced for a new Laptop.
A new laptop to replace a totally Matte finish 1600 x 1200 screen laptop with decent backlight is seriously expensive and wider. 16:9 is too wide. 1080 is worse than decent 2002 screens.
It's only cheaper to get a new laptop if it's a very basic usage, in which case perhaps Browser + email and Libre Office on Linux will do anyway. Cheap laptops have too rubbish a screen.
But Win10 is going to be mess. So I continue my hybrid research:
1) Native Applications on Linux
2) Some windows applications on WINE
3) Really old stuff in DOSBox
