1/80 is fairly slow and you were at F/4.
Have yet to see a Canon P&S camera disappoint and I still think highly of my aged and beat to schit S40 PowerShot Dinosaur.
One that particular camera, there is very little in the way of manual override...In hind sight, I should have perhaps tweaked the the ISO setting to gain either more speed or another STOP...
But looking at your picture above, its a nice picture, but point to one part of it that is in pin sharp focus??
[bleep], maybe its my monitor thats the problem?? lol
Now have a G12 courtesy of Santa, so hopefully that will cure some of my woes...
