Samsung Dex [0] is bringing that vision back, maybe?
When I travel for personal stuff, I now just take my personal laptop and my phone. If I need to get into my work stuff, I'm pretty damn effective with all the cloud tooling I can get into from the browser under Dex. Screen real estate is the biggest issue which Dex handily solves, with a close second being things like MS Teams being a little clunky in Dex mode (not a dealbreaker). It's all more than sufficient when I get pinged on personal travel, since I'm not likely to need to be at 110% like I am if I'm working at 2pm on a Tuesday.
Why would I want to do this? Because every time I take time off, something goes off and nobody knows what to do about it, so I get pinged.
Part of your personal brand at work should be "not the guy who is always losing his work laptop".
Plus, my personal laptop is cheap, old and encrypted.
If you'd lost a work laptop ever than yeah I could see not wanting to lose another one, but the mere possibility of losing one isn't anywhere near being "the person who is always losing their work laptop".
Losing my personal laptop would be a big deal for me. Losing my work laptop, while still not ideal, is just what IT calls Tuesday.
For what it's worth, I've never been caught up in the 10+ rounds of layoffs which have taken place in my career across all the places I've worked.
