I'm the same.

When people who maintain this separation travel for work, do they just bring both along? My laptop is often the heaviest thing in my bag, I'd hate to bring two.

[late edit: I meant work travel]

Yeah, I do. My personal laptop is a Macbook Air, so not too much of a burden.

I don't generally bring either. If I'm traveling, I'm on vacation.

Last time I travelled for work I brought only my work laptop.

But I do commute on bicycle with both in a bag clipped to a child seat. Combined weight of the devices is 4kg.

I believe they do not bring work laptop. A separation is a separation.

Travel doesn’t always mean vacation, or work. For me, it’s rarely only one.

I very rarely use my personal laptop. I stream on my phone, if I want a bigger screen, I either cast or use the app on the TV. So for me it's work laptop and two phones, not bad at all for the peace of mind. I literally turn off work. I used to run mixed, and I really wish I had changed earlier.
