While I'm not an Android user, I have followed this release cycle with interest. If I were a Note user, I would have no issue upgrading to the Note 5; it seems like a great device. Samsung seems to have brought this to a mature market with the features most people want on a modern device.
Having said that, and as one who's been a designer myself, I know the designer, or design team leader is KICKING themselves right now, thinking "Why didn't I foresee this?" All good designers try to anticipate every potential end-users actions and try to protect against the device destroying itself should some weird action be performed. As such, I wouldn't call the SPen design a flaw, rather it's a design 'oversight'. You can bet they won't make the same mistake again, due to the PR hit they are taking on this iteration.
