the one thing linux really hasnt been made on par with winblows yet is the dreadful amount of options for android simulation -the most popular choice seems to be Waydroid, but its such an unneeded hassle to set up at all -genymotion is just slow -and than you have things like android x86 which entirely defeat the point of an emulator
Yes. Many. Blisslabs has partnerd with EIDU to work on tablets for low income countries. I personally have sold android boxes with Bliss. Ax86 has a large number of sponsors that are/were casinos. There are people working on using it in cars. 2-In-1s. ETC.
VMs are the minority use case…
