Can't decide between this and the iPhone 5...

I'd say try it for 13 days. If you decide WP isn't for you take back and get the IP5. I'd recommend giving L822 a look before making a WP decision though.

Ehh, I like the Lumia line, but the main reason why I want this one over the 822 is because of its form factor; it's incredibly easy to hold, and I like the style of it more.
 
Do you use your phone as a music player? If so, right now WP8 + music sync'ing + adding songs etc is a bit of a mess... You can work around these, but I guess if you have a lot of music already in iTunes if could be a bit of a mission.

And yes, many times I do if I don't have my iTouch with me. I especially would with the 8X because of the Beats Audio... Is the music syncing that much of a hassle right now? Ugh I really don't wanna go with the iPhone but everything seems so much more simple! Plus I can get more internal storage with it....

Guess I still have some decision making to do lol.
 
I have an iPhone 5. I love it. It is an amazing phone. Having said that, if you do not have an iPad or Mac, I would highly recommend trying windows phone. Apple makes great products and has an ecosystem that in my opinion is unrivaled, but this comes at a cost. As you have found with your iTunes and app collection, once you get invested in an ecosystem it is VERY difficult and costly to leave it. If I didnt have an iPad and Macbook I would have gone for a Lumia 920 but I use iCloud way too much to use anything else and I love iOS so I am not upset about it being boring.

I would say you should try Windows Phone and see what you think after a couple weeks. Also, the rebooting and other bugs will surely be fixed soon. Microsoft and HTC are going to get things working properly for their users. I wouldnt worry too much about that long term.
 
I've been agonizing over the same decision.

I had an upgrade from an iPhone 4 on AT&T.

I agonized over all the WP8 phones. The 8x was too low on storage. The 920 was too bulky. The ATIV S might have worked if it ever came stateside.

But eventually I went with an iPhone 5 (and my wife got a 920).

I'll say this about my iPhone: it just works, and it is fast. I'm tired of iOS, I really am, but it's the little things, like universal background audio, car audio connectivity, picture copy/paste, "undo" support, mobile browser site support, multiple synced email folders, the list goes on and on.

I love WP8 for what it does well, but it's still so young. My phone is a tool first and foremost, and while it makes me yawn every time I look at, the iPhone is, for me, a better tool. At least for now.

I also tell myself that if WP8 improves in the next 6 months and/or ATIV S comes stateside, I can always sell my iPhone.
