Maybe we can take this post as an opportunity to discuss alternatives, specifically to the Latitude 5420/7420/7520 series notebooks. What can you recommend?
I bought a refurbished Fujitsu Lifebook a month ago after 7 years of using various Dells and Macbooks. The experience (on Linux) has been surprisingly smooth. Everything just works, zero overheating. The machine has thinkpad-like build quality but it looks nicer.
