You can dual boot a Mac, also can run Parallels OS, having both on screen side by side. I’ve done both.
Really depends what your needs are.
I use a Mac Air from 2015 as my travel computer. I got it used in 2022 for $220. Shout out Jade Skyy, she put me on to Mac.
It does everything I need on the go. I have the 11” model, i7, 16gb ram. Custom ssd at 1TB. Got it cuz it’s soo small, shit fits on my airplane food tray with space for my coffee/snackz. Coming from a 17 inch MBP I am just soo happy with how little it is! I have an IPhone 13 Mini so they can be tiny friends together. What a cute couple!
My home office features one big rig windows OS computer, Ryzen 5600x 4.20ghz, 32gb ddr4 4000cc ram, Nvidia 3060 12gb vram. I used for gaming and crypto mining. Super custom setup I made for my self. Cost me 10x what my Air did and I use it sparingly, cuz I don’t game like that these days, also never home. So it’s just a miner now.
Most of my older computers I have turned into Linux based crypto miners. This allowed me to keep using 15+ year old tech efficiently, cutting power costs way down, while still profiting. With Linux OS you can truly customize everything about your computer system. It will breathe new life into what you thought was a brick.
