Talk:Update paths

It's unfortunate that external applications are being wiped out with each OS update. I know that some folks consider this to be a feature, not a bug, but I can't really test new builds on the laptop if upgrading wipes out my whole carefully configured environment (external applications that aren't .xo bundles).

Online updates not requiring AC power?

You note that AC power is not required for online updates. Is this true in all cases? How about updates that might also flash the Firmware. Or is there no such online update variety?
