Actually, there is 1 or 2 cases with cracks in the P70 too. Plastics are just as thick as on my T60p palmrest, but it is of a different "structure", and definitely does not flex as much. From what I see on the base cover, the plastics seem to originate from Samsung, so the bezel might as well too. My T60p seems to have plastics originating from Mitsubishi. I might be wrong though, so please take this with a grain of salt.
Puppy, yeah I saw your comment before it got deleted
. I thought that it might have been somewhat out of line, because it could've been understood as an insult on "psuturtle" which is apparently trying to get the slow, old, elephant (Lenovo) to realise they must put out what potentially can become a very large fire on their "burning platform". But I definitely understood you intention.
On the other hand, Lenovo's forum is in my opinion hopeless. It is impossible to criticize, when criticism is due, especially if you are too bold in your language. E.g. there's no way to describe how outrageously bad Lenovo can treat their customers without getting yourself kicked from the board in the end. But I suppose this would apply to any "manufacturer" forum.
