My local dealer got in 462's (carb version) on Thursday. Curiosity drove me to go and check them out. First impressions of the saw are pretty good, IMO. I mean, I didn't run one, so just from handling the saw and checking out the features, they are very nice and lightweight. Very streamlined and Stihl has taken a lot of care to tidy up unnecessary space around the saw to make them lighter weight. The ergonomics feel right. Distance to the brake flag, handle angle and throttle/operator presence all feel natural in the hand.
Something I noticed when I was looking at all the Stihl saws, was the variation in accessing the air filters. The 462 is flat screwdriver bolts, whereas other models are T27 and some tool-less.
