And I respect that opinion... I will just repeat that "anyone can be an asshole given the right situation". If you haven't had the experience of more than one developer of software or hardware come off as an asshole, you've been in contact with way too few developers is all I'm saying and if you want to base your decision on what to buy on such an isolated event when you don't even know the person, ultimately you wouldn't buy a single thing for the risk of someone acting like an a-hole towards you which can and will happen given the right situation since in most cases WHEN that happens it very seldom has to do with YOU but some other situation out of your control.
I'm sorry if you took offense, that statement was not directed towards you in any way. Just saying... buy what sounds good to you and leave all those other insecurities at the door is my opinion.
