This is wonderful in theory but I've purchased laptops pretty recently (Thinkpad x200e) which I didn't fully vet before I purchased. This laptop had lots of issues. Non Working Wifi, couldn't sleep correctly and had issues with sound.

Having everything work out of the box is not guaranteed. Ubuntu is generally better about it but not all distros have the level of workarounds that Ubuntu does. As far as ACPI is concerned not even Ubuntu is decent.
