I'm looking to switch to either a P1 or X1 Extreme. I think those would be better equivalents with even better hardware: more max RAM (64gb), 2 SSD up to 2tb each, OLED screens on the 2nd gen versions (on X1E currently and soon on the P1 I understand), better keyboards etc. My company will be buying me one soon. As far as software, for me, after almost a dozen years on OS X, using Linux is superior in almost every single way mainly because of jumpapp [1] and customization (I prefer KDE). Some rough times when first installing with crashes / having to reinstall but it's been stable more or less for months.
