>I installed CM7 stable, she gets push updates that are seamlessly handled via Rom Manager. Does this work for major updates? As far as I know when you want to move between major versions (the next one is 7->7.1) you have to basically wipe the phone and start from scratch. Because most Android apps use local storage that isn't synced to the cloud, to actually keep your data you'll have to use hacky things like Titanium Backup that may or may not corrupt data, particularly so for system settings. The biggest shortcoming I see in CM is this, the lack of a good Over The Air upgrade method that keeps your data. Ideally I'd like to see Google offer APIs to apps so that their data is continuously synced to my google account and then upgrading or getting a new phone would just be a matter of logging in and letting it sync for a while, making it closer to a ChromeOS experience.

I've gone from super alpha CM7 to CM7.1 and current nightlies without wiping, save for once, and that was due to Google Apps changing. CM6 -> CM7 you have to wipe, but most OTA updaters will tell you that the OTAs from Eclair->Froyo or Froyo->Gingerbread effectively require a data wipe anyway. My mother had issue after issue after the Eclair->Froyo OTA and they went away when she did a factory reset (wipes /data). >Ideally I'd like to see Google offer APIs to apps so that their data is continuously synced to my google account They exist, though there is some fine print about device compatibility that is a bit wonky and NO one seems to use them for anything. I agree. I think this is the missing feature in a large way. I hate having to remember to turn off the loud beep in QR Scanner when I wipe my Droid (it's speaker is sooo incredibly loud). Things like that would be trivial to store in text config and/or sync with Google.

I just checked and 7.1 doesn't require a wipe, I was under the impression that it did. Is it that only when the upstream major android version changes that you need to wipe? A quick googling leads me to believe at least Google's official OTAs for the Nexus line don't require wiping.
