Are you using one, which one, and why? I started with the Palm Treo 600, then the 650. I really thought they would be the shit for a long time. Hp ruined that. Then iPhone up to the 4s. I liked it for a long time but I didn't feel the upgrades were going anywhere for me. Hate the io7 look so in April this past year I switched. Nokia Lumia 1520 Windows Phone 8.1. So far this thing has been my favorite. Business wise it flows with Office365 so well & OneDrive I use it like a tablet all day long. Then when I finally get on the laptop everything I've done is already there. iCloud was never that fast, but I didn't use office on the iPhone. Unfair comparison probably. I like the media apps better, but have ran into a few nags with apps not fully developed yet. Haven't used android. The employees I have that do always have problems, I think its them not the phone. And I don't like Chrome, so I just never tried it.
