I did the same. Nothing nefarious on my work laptop, but I used it for websurfing (avoiding questionable sites), booking trips, etc.

Then I realized how stupid that was even though my employer was fine with and was never strict with how a work laptop is used.

I realized not only did I not want my work to know what I'm doing on my personal time, the risk of cross-contamination and being accused of stealing confidential documents or a personal text making it look like I'm doing something wrong is too high.

I bought my own cell phone and laptop and now never use my work equipment for anything but work. Not worth the risk.
