Then I was a nice guy and cleared the driveway of the little old lady who lives alone across the street. I discovered that the blower could handle snow all the way to the top of the intake housing with only a very little bogging down, and that with the speed control set to 2. If I'd shifted down to 1, it wouldn't have complained. By the time I finished that, the snow spray was freezing my forehead, so I packed it in.
My iMac paniced twice yesterday with a message that indicated a possible hardware problem. It hasn't done it since, but I got nervous and started looking at prices.
It turns out that a 20-inch iMac G5, fully loaded, is about the same price as a 20-inch Cinema Display and a fully loaded Mac mini. The latter gives me the ability to upgrade the system later to a G5, without having to essentially throw out the display as I would with the iMac. OTOH, that does only give me a G4/1.4 instead of a G5/1.8. Even so, that may be the route I go if the iMac does bite the big one.
