I think its an excellent money maker for Stihl .............. that said, I don't want one. Its great for previously stated weekend warriors that would actually take the time to reposition the laser for the two face cuts and then again for the back cut. I don't see any production minded soul using it though. Thats my opinion on using it for dropping a tree.
Now that cut to length idea, uh, that won't work, unless you are holding the saw really level and there isn't any swell or crooks in the tree, but again, weekend warriors, buy everyone one you can get.
I would also have to reposition my mini tachs and I don't want to do that, LOL.
