Regret
A few years ago I had the highest spec Surface Go 3. Windows ran absolutely awfully on it. It would regularly freeze and slow down because I was using Microsoft Office (crazy, I know).
Installing Linux on it is something that never even crossed my mind back then. It makes me sad because I ended up buying a Surface Laptop 7, which is super nice in terms of the hardware and build quality, but now that my interest in Linux is growing, I find out that Linux will not run on this new laptop.
I wish I had kept my 1000 euros and just installed Linux on the old Go 3, that would have been perfect. Instead, I let myself get lured in with pretty hardware, to be even further locked down into Microsoft's ecosystem.
Can't wait to sell this thing.
