Agreed on the Note redesign point. You are, however, off base with the naming/numbering scheme.
First, there's no conclusive evidence the next iPhone will be called iPhone 7.
Second, Samsung skipped 6 to align the brand experience with the Galaxy S7 since they're both 2016 devices. I'm pretty sure their 2017 offerings will be Galaxy S8 and Note 8.
The iris scanner is infra-red and works with both glasses and contacts - only the setup requires their removal. It also works at night. Sure it might be a gimmick but then again, when using a phone with gloves it gives the user another unlock option. Gimmicks do have a place in changing the thought paradigm and spurring on innovation.
It's OK to be an unabashed Apple fan, however, you come off a something of a cult follower; unable to do proper research to support your points - not a good look.
