On the updates side you can always enrol for the developer program and get updates straight away. Although my HTC 8x' battery isn't as good now I'm running WP8.1.. Still worth the update its much better than WP8.
No unlocking, rooting and stuff involved for patching a Windows phone outside of carrier-pushed updates?
Off topic, but what went wrong, I've rooted three Samsung Androids no problem.
My first time trying.
Oh well. I'm not regretting it now since I split my investment between cheap phone and decent camera (dang, digital cameras just keep getting smaller and cheaper). If there was a non-iPhone sized like the Samsung Galaxy Light but made from top-quality materials like a Surface, running either Android or Windows (I'm willing to convert to the latter if one doesn't need to tinker overmuch for Windows updates, along with Office integration even if basic), that'd be perfect! Given the popularity of iPhone, why can't OEMs see the market there? Some of us prefer upgrading-plus-downsizing. Otherwise I wouldn't have been interested in the Surface at all.
