Same here! Running an X250 with 8GB of memory and an i3 for engineering in university. Of ciurse I'm not doing any simulations or computations with it but for everything else it's an absolute dream. One of the last ThinkPads to have the hot swappable battery system and it's highly repairable. 12" screen size is perfect for an on-the-go laptop in my opinion. I'm running Fedora with i3 on it to maximize the screen real estate I can get out of it and it's lovely. Even compiling programs and similar sctivities aren't a bother to be honest. Very happy, let's hope it stays with me for a few more years!
