This isn't directly related to the tiles but I don't feel like I can recommend WP to anyone non-technical, which is weird because it's a very simple, user focused design. For me the issue is that often things just don't work. I've got a Lumia 920 and I have
- plenty of freezes and resets (more when I first got the phone and less now after firmware & OS updates but they still happen more frequently then I'd like)
- apps often exit unexpectedly (a problem for the app devs, not the OS but I never had this many issues on iOS & I've had crashes from Bing News recently which is an MS app)
- mysterious & severe battery drains (seems to be a common theme on these forums)
- things like Internet sharing not working, sound only coming from 1 headphone, Bluetooth not working and all needing a restart to resolve
Compared to the iPhone 4 I had previously and my wife's iPhone 5s the Lumia 920 is downright unreliable, and from posts in these forums it doesn't seem uncommon for any & all WP devices to suffer these issues. I like my Windows Phone, it has some very nice features & I'll probably buy another, but if anyone non-technical asks me for a phone recommendation then I can't say WP.
