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…
Also I personally think the keyboard topic is totally oversold. I'm quite content with the stock X230 keyboard, and I would swap in a heartbeat if I wanted to (it's two screws). And my previous laptops were T22/T60/T61, so I do know the difference.
