For me (personally) to consider Dell again, they would have to replicate everything that Framework does and ship Linux with support.
Edit: can I also add that they suck for business too? The slim form factor has NO place in business, slimming down the chassis and removing ports is an anti-pattern. I couldn't give a shit how thin my work laptop looks, my job doesn't involve taking pictures of unrealistically minimalistic office desks. With Dell you either get a dainty oversized netbook or a rugged behemoth (which is a little too rugged unless you're in telecom and roll in a van). Where's the middle ground? Nothing needed to change from the old thinkpad.
