I doubt I will benefit from that. The phone is bought by the company and I pay back the initial price of the phone. Since it's part of the Enterprise contract any 'normal' consumer promotions aren't available.
I use the stylus a few times each week but not daily. Since my N4 is pretty banged up, there is a good possibility I will keep it. I will still use it for media consumption.
I like the simplicity of the Apple ecosystem. One mail app, one photo app, one calendar app, iMessage. On my N4, I used INBOX for exchange and GMAIL for other mailboxes. I still have Exchange specific issues (ie: like when someone update a meeting request). I use google photos for sharing my pictures but use gallery & samsung app to take them. I create folders in Samsung Gallery but Google photos doesn't keep my photos organisation and I have to double manage everything. Contacts management in Android/Google is more cumbersome. I often have to edit address, phone number that don't auto-format themself. I use Textra for SMS but sometime I switch to something else because it's not 100% reliable. I used Cloudmagic but they now went to a subscription based model 65$/year (exchange support was flaky too).
I don't think I really use something that is Android specific (my N4 doesn't support Touchwiz theming). I have a clock & weather widget. I get occasional reboots (1-2 times/week).
Not sure about the battery life of the iPhone 7 but I'm fine with the size. I work on computers (home & at work) so I don't spend much time surfing on a tiny phone.
The main purpose of my phone is for entertainment while I'm commuting (2h/daily). I listen to music or watch TV shows. Beside that, I send text messages to people all know (99.9% have iOS devices).
I'm thorn..
Note: I like the GEAR S3 and dislike the AppleWatch. I think the Tizen based S3 will be compatible with iOS.
