"My Computer" et al. sounded patronising and childlike when it started and continues to do so now.

How about just "Items" and "Photos"? Unless there is something marked "Someone else's items" and "Someone else's photos", is it necessary to specify that they belong to the user?

I actually create a "my" subdirectory in my home directory that I put all my stuff under (~/my/videos/ ~/my/dotfiles/ etc.)

This is a reaction to being fed up with OSs and programs putting things in the predefined directories without asking.
