Since the 830 is essentially the same as the 2-year-old 920 (but with half the flash memory), why pay $400, when you can get the 920 for $175 on eBay? Bragging rights?
Can you confirm that the Lumia 730/735 does *not* work with the Nokia Glance Screen? That would be a deal-breaker for me.
Looks like a solution looking for a problem. I've never had even the slightest urge to participate in synchronized swiping of photos.
Why is MS Research wasting time on these silly apps?...
As a 620 owner, I agree. The 630 is no 620-replacement. Lower pixel density, no NFC or flash. No thanks, I'll keep loving my 620 with 8.1 DP.
