Just upgraded to it yesterday from a Droid Bionic, which was a pretty good piece of hardware, never supported correctly, but that's a topic for another forum. Spent a couple hours last night setting it up. If you're tech/phone savvy at all and familiar with either Android or iOS, you'll have no problem. The interface/settings are clean and simple, pretty intuitive, maybe a little on the minimalist side. Reminds me of the Xbox One, no surprise, with MS apparently intentionally limiting what you can even see, never mind change. For the average user, it's not a big deal and even I'm nitpicking a bit. Speed and display are great. Form factor is about as big as is manageable, i.e., being able to sit comfortably with it in a front pants pocket. I'm liking the tiles, makes me better appreciate what MS is trying to do with Windows 8 and I love being able to delete any app, especially Verizon stuff, very cathartic. No major setup issues - syncing with Exchange was simple, email client blows away what I was used to, and I got my few go to apps installed and working with no problem. One complaint on that front is the Citrix Receiver appears to only support a single account. At least I can't find a way of adding a second account and I went into every setting I could find. But it works and for business users, that's big. It was one of the reasons I held off going to WP until now. Call quality seems decent enough but I didn't spend much time talking on the phone. My biggest gripe, no alert notification/light. I know, I know, 8.1 is on the way but it's 2014, you shouldn't have to unlock your phone to know you have texts/voicemail/email/etc. Even the original Droid in 2009 had an alert light. Anyway, nothing is perfect, I'm happy about the switch so far, and I'm excited about my phone again. That pretty much says it all.
