Taking the laptop to the office and back home again daily. The hinge has gotten weak over time. The connection to take off the screen is very fragile, tapping the button to enable removal only works about half the time. Then, when re-attaching the screen sometimes it doesn't catch, or the keyboard connects but doesn't realize it is connected so the machine stays in tablet mode. The trackpad has gotten spongey and harder to click.

It didn't happen to me, but of the 4 people in direct team that had them, 2 had battery issues where the battery expanded making the laptop unusable. *Edit: This was covered under warranty, thankfully

This is from approximately 2 years of daily use for work. I no longer use my surface.

I typically care for my laptops very diligently. I still use my MBP from 2012 and it works like a champ. I don't have a windows laptop anymore, but my main desktop is windows. I'm not a Mac fanboy.
