Tentatively, I'm saying YES! YES! YES! I would re-buy it in a heartbeat. It's GREAT hardware without a doubt.
The bugs people are experiencing are definitely Windows Phone 8 and software related. Things that can be fixed, and since it seems like they're experiencing similar issues with the 8X it points to Windows Phone 8 and not just Nokia.
To me, this means that maybe I was wrong about the purported delays in Windows Phone 8 development... it really seems like it was rushed and incomplete to meet the launch deadlines.
It's very disappointing, but it happens. We saw the same thing with the iPhone 5 launch. Heck, I've seen it with several phone launches in the past 5 years.
What the real question is... how quickly will Microsoft respond to these issues to produce fixes? Honestly, if I don't see a fix by Christmas, I may move back to my Titan or 900. The handful of glitches I've experienced aren't showstoppers on their own, but together for an extended time, they will be. Plus, the improvements to WP8 aren't drastic enough (minus the start screen anyway) that I can't live without them.
I'm actually more scared about the prospects of a 7.8 update being rushed.
