Ahhh, the thin kerf blues! My cordless circular saw suffers this as well - thin blade that gets all wambly when it heats up on long rips. I suspect the thin chains are an attempt to maximize battery life, and that going wider will lead to fewer cuts per charge. Semi-related, I've used four different brand electric chainsaws now that rely on those thumbwheel thingies to set chain tension, and every one of them has thrown the chain at some point or another. My solution was to switch to a cordless sawzall with a real long pruning blade.
