Personal laptop is much thinner and lighter, and I'm less concerned with losing it on travel compared to my work laptop. Also - accessing work resources requires a crap-ton of security policies applied to the device (full control including remote wipe, a stack of security & endpoint management software, just to be able to authenticate with my work account) which I don't want to install/grant on my personal laptop.
That's an interesting value system. Why is losing a work laptop more concerning than losing your personal laptop? losing either of them isn't great, but the company has far more resources than you to protect and replace the laptop than you do.
Yeah but it's yours. Replacing it is so much harder for you than it is for corporate IT which buys laptops by the pallet.
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.
