I don’t mean this as an insult, but I am surprised whenever I hear of someone using a work laptop for personal use. So much risk for very little upside.
Are you willing to bet your primary method of paying your bills and funding your entire existence that your company isn’t using monitoring software and that you’ll never accidentally pull up a NSFW scene on Netflix?
To me, a $329 iPad is a pretty cheap price to pay to never have to worry about that.
Netflix app is available on windows store (aka not blocked by IT). I carry the laptop cause I need it for work, I don't want to carry an additional large screen device.
I have always just dealt with a second device because I have no interest in doing anything on my work system that isn’t work.
That includes basic stuff like checking personal email on a large screen.
Activity monitoring software is far too common for me to be personally comfortable with doing something as basic as watch Netflix on a work system. All it takes is one screenshot of a romance scene for my company to accuse me of watching porn on my work system.
An iPad added to your bag won’t break your back or your bank.
I understand your mindset and also live this way, but we are the outliers. Normal people don't see a risk with this, and the upside is that it's there.
