I still love mine, and I love the replaceable battery and the fact that you can still get batteries. but best laptop in the World? I do use mine, occasionally, it's a great work horse around the house for network things as it has an ethernet port. but TBH I use my X1 laptops more, the ability to USB-C charge is near critical now, and the X220 lack of USB-C as well as low res screen really does mean it's not a machine…

which is absolutely fantastic.
What you are looking for is a USB-C with PD support, which means that the devices can negotiate the amount of power that is being sent!
