Ah, the Windows Phone tile does not resemble BBDM at all. When your phone is plugged in it allows you to sync music and photos to your phone, then from your phone to your PC (if you go in and select each individual photo/music album). Unless I have missed it there is no all-in-one back up that moves your whole device into an archive onto your PC. It also has a link to the Windows Phone market.
That being said, BlackBerry Desktop Manager is no longer being used. BlackBerry Link is what you have to use with the BB10 phones. It does have back up and restore capabilities, but it doesn't give you granular control over the things you want to back up like BBDM did. It is almost an all or nothing deal. You can choose between Application Data, Media, and Settings or a combination of the three. Which isn't too bad, but I do wish I could drill into Application Data and choose what I want to save.
I'd say if all else is equal except the removable battery and microsd slot between the 928 and 822, then the 822 is probably the way to go.
CHIP72, BlackBerry 10 has taken care of the need for reboots and battery pulls. My Z10 had rebooting issues initially, but that has been fixed in an update (that Verizon has NOT gotten around to releasing - thank goodness for OS leaks).
My Q10 has been rock solid. I have done all kinds of unspeakable things to it since I got it and I have yet had the need to reboot it. The screen is small, yes, but it isn't that bad and it gets the job done. Of course this is coming from a guy who preferred his Bold 9930 to his Galaxy Nexus and the screen size difference wasn't an issue.
For someone with a BBOS device, battery pulls don't happen as often as they are made out to be and I think one of the reasons I have yet to switch to even a Q10 for that matter. In the event I do reboot I am back within 2.5 minutes. Cumbersome but acceptable considering the uptime. And as far as finding an alternative for BBDM in either BB10 or WP, I guess I'll just have to live with it.
I guess the biggest question is how I will react to notifications. Other than that it seems the 822 is a strong contender for me.
