Yes, ThinkPad is great for Linux. Only had/have a few but always a pleasure to use. So reliable. Plus I really don't like touchpads so ThinkPads for the win. Even have two ThinkPad standalone keyboards (one wireless, one wired) for when I hook up to a mobile device, media box, or mini PC.
T21, Pentium III - Slackware 12 & Windows XP
SL510 2847DKU - MX Linux 21.2.1_(respin) FVWM_Ext, OpenBSD, and Void Linux
E15 Gen 3, AMD Ryzen 7 - Slackware 15
X1 Carbon Gen 3, Intel Core i7 - Fedora KDE Plasma Mobile Spin
Anyone know if it's possible to use the SIM slot in the X1 Carbon? Also, any recommendations for an alternate distro that is ideal for that laptop/tablet combo?
Sounds like one of those Why Waa Waa questions. There's currently only six browsers listed, at the moment. It's not some all inclusive thing.
Where's Fennec, where's IronFox, where's WebLibre, where's Cromite or Helium or Tor Browser or or...?
Give these kinds of lists and the organizers time to check and test things or get additional feedback.
