If security is something you place a value on... And if the type of security features that BlackBerry has added to the Idol 4 is something that makes the DTEK50 of interest.... I think many here probably don't like a locked device so they can't root it.
For the average person that if fine with Android security (who knows anyone that has been hacked?), then not on specs along this phone isn't going to interest many. It is an enterprise/goverment play, and that is who their customers will be... just probably not in the US.
