Honest:
I know you love the 8X - the screen, the way it feels, etc. Would there be anything that lures you at all to the 822?
There are plenty of things that are good about the 822, just none of them are for me.
Most important specs that make the 822 a good choice:
1) SD Card slot
2) Nokia Apps
3) Removable battery (I've never had an issue with built-in batteries but some people are paranoid)
4) Inductive charging
Also, I can't say this enough. While the 822 is definitely a budget phone and looks/feels cheap, it isn't nearly as ugly as the photos that have leaked. It's a little charmer in person.
EDIT: I've learned that the black and red 8X are exclusive to Verizon, so that means T-Mobile and AT&T will only carry the yellow and blue. Kinda sticks because I know a lot of people who thought the yellow 8X was sweet, but I'm probably gonna go red.
