Haven't done anything with this yet...crack is stable. I'm not using that one much as I kept it with 9.2.2 and browsing using Classilla is an "occasional" thing with me.

Both of my Lombards have cracks in the same places. I guess the CPU puts out more heat than the Pismos. I doubt they changed anything about the plastic itself from one model to the next. The heat pattern must just be different...
