With ~zero unix experience (I was moving from BeOS), I ran FreeBSD full time as a chemistry grad student from 2003-2009, on a Dell XPS, and mostly had no problems. What's changed?

(I'm interested in leaving linux and going to FreeBSD)

Well the problem is not a lot. It's pretty much like being in 2009 still. Which is fine if you didn't adopt a huge amount of technology changes since.

I mean I quite like the todo list that comes with my phone and computer and syncs flawlessly between the two of them. Ships with none of that shit.
