Not often enough for me to really notice.

I use my MBP around 10-12 hours a day, maybe more. I don't love the finder but never really have bugs exactly.

Time machine isn't great but it's ok. It gets stuck if you don't have enough disk space.

The other things don't really affect me.

My biggest gripes are around Spotlight. Have you ever tried to search for a file or or create a smart folder that works? These features are horrendous. And Cmd+Space [type app name] used to be a decent app launcher. These days I often find it sits and spins and I end up using the Finder and navigating to Applications -- and that's faster than Spotlight.

When I actually need to find a buried file, I drop into a terminal. Then I feel sorry for people who don't know how to do that.

I've never tried smart folders - I didn't know that feature existed.

Search is mostly ok for me.
