I had XPS 15 before I had the current M1 Macbook, and before that I had the previous gen XPS13 for a very short while - I had to return that, I couldn't work on it at all due to overheating/thermal throttling. XPS laptops are incomparably worse machines and opting for that instead of a Macbook was my greatest mistake that I'll never repeat (I also really tried to like Lenovo machines, but that ship has sailed too - I'm going Apple only since this Dell experiment).

I never lose any stuff on my Mac thanks to the seamless integration of iCloud. And the motherboard fire that happened to my XPS15 destroyed the SSD anyways...

About the screen... Don't even talk about that. I was so angry when I first saw it - I paid big bucks for the best screen Dell offers and yet it's so much worse than the screen on cheapest Macbooks (I moved to the XPS from Macbook 2015 - even that old machine has a much better screen). It was flickering when I enabled dark mode in my editor (not a faulty machine, I tried to return it and they have shown me that every machine does it)!!!

And no, the battery life is nowhere near the 2015 Macbook Pro, and absolutely nowhere near the M1 Macbook. The ads say so, but it's totally not true - my MBP2015 still can sustain 6 hours of work with the original battery, while the XPS was dead after 6 hours of not doing anything.

And to top it all off, the whole XPS was creaking even if I just put my hand on it, and raising it into the air made sounds so terrible people around me were having amused looks! None of my Macbooks ever made any sound like that - or any other unpleasant sound whatsoever.
