I don't know why people even care about that. I go out of my way to not use my work laptop for personal work/projects/etc. Especially considering the amount they value the laptop at (which may be inflated) is deducted from your severance payment
From my experience, not many people set boundaries between work and personal tasks and the number of people who have personal software projects outside work is tiny.
I too am guilty of using work laptop for personal work like shopping etc couple of times.
Personal anecdote:
one of my colleagues was recently discussing about replacing his 6 year old laptop that he rarely uses, one of our architects commented : "I don't understand why anyone would need a personal laptop at home. We can use our work laptop for anything that our mobile can't do". I was surprised to hear that from an architect and even more surprised to see many others nod in agreement.
On the one hand, having complete separation of work and personal electronics is a best practice. On the other hand, most of us don't carry two phones or two laptops when we travel on business.
If I were a senior government official or in some other high profile/sensitive role I'd probably be more conservative but it's pretty common to use some combination of personal and business-issued devices for everything.
