I don't like that Lenovo is put shoulder to shoulder with Apple here. I have never personally owned a macbook, but my SO has and they are multiple classes above anything Lenovo has made in the past decade. My work gives me a P1 and I liked it for the first year (especially with that mobile xeon with every ISA extension on the block), but I am growing tired of it. Here is the short list: the touchpad drops out, blue screens, thunderbolt dock driver issues, docked displays needing to be unplugged/replugged multiple times, waking from sleep mode without my input (good reason to never use this for a laptop that is used on the road), failure to wake from sleep mode (full speed fan and black screen until the power button is held for 30 seconds), the laptop deciding to say "locking" for a split second then going to sleep while you are in the middle of working or presenting.
Macbooks are not perfect, but lenovos are not good.
At the end of the day, it doesn't matter to the end user whether it is due to the OS maker or the hardware manufacturer.
That distinction would only matter if the comparison was limited to Windows laptops only, because that would establish a baseline that is the same for every single option. Some people want nothing to do with any OS outside of Windows, and that't their choice, nothing wrong with that. Once Windows-only limitation is gone, that distinction becomes kinda pointless.
