I do, I've got a long time without one now. Had one for a few months but that was all. The new ones are super light and thin which is pretty cool and even more processing power than the iPhone 6 if you go for the larger model.
if i'm literally on the road and someone calls i'll use my GFI Max App/Team Viewer to hop on and fix lil urgent issues. (yes aj, i use my phone while in my vehicle, but i pull over).
Speedtest. Let me tell you, teamviewer on the iPhone6+ is actually usable lol
