FWIIW, I just got mine and it almost exactly covers my expenses from my just-completed vacation in Jamaica and Mexico.
Hard to say whether that means I spent it there -- I would have had those expenses, stimulus or not. It didn't change my plans and I haven't spent anything I would normally not have spent anyway. The fact I didn't move a few bucks from my "hot" savings account (this is my "pay myself first" account I use to pay for things like vacations, TVs, etc. -- I ALWAYS pay cash) --which I was going to do -- probably means that I have put the check into savings, from one perspective.
But $1,200 just isn't that much. It's better than a poke in the eye with a sharp stick, but it just isn't that much.
