I can't help but be thrilled at how awesome this is. The camera is top notch, the screen is amazing, the battery life is... haven't had long enough to last it. Seems really good for my use, though. Haven't tested the call quality. IE 11 is amazing, though it has some hiccups with me sites. Most of my apps are there, the others are likely to never be there (Clash of Clans, Final Fantasy WotL, Infinity Blade 2). There are a couple minor things that bug me, though. A) Apps still crash sometimes. I know it isn't the RAM, I have plenty. I know it isn't a weak processor, it's a strong one. Yet My Talking Tom still sometimes crashes. It isn't as often as my 520, but it still happens. B) Apps are just blown up. Mail looks the same (bad, in my opinion), and all other apps so far do as well. The screen is gorgeous, but the apps just seem to be same-y. Maybe that's just an issue I have. Maybe somebody can point me to apps that take advantage of the larger screen size. I thought that I would have problems with the size, yet it fits perfectly in my pocket (with a case on, obviously, it's still a huge purchase and I'd rather not break it). It's also the perfect size to watch videos on (when I get them on here). This might turn into my mobile internet thing for a long while. Perfect size for me. Also, I love glance. Be prepared for an updated cat picture as my avatar as soon as I get a good one.
