WP7.5 deficiencies compared to iOS 5

That was my point, that Zune also syncs over Wi-Fi when you're charging.

The only difference is iOS 5 allows manual sync without charging, and it can backup wirelessly to iCloud or iTunes.

Not for Mac users :(

Also, the bigger issue is backup and without that, WP7.5 is pretty crippled.

Oh yeah, I forgot LOL. And I was running Mac too just a week ago! I guess it's because I never really sync. =/

Yeah, I guess backup was one of those things that they didn't get around to in time. :(
 
Nope, apparently it has to be plugged into power AND Zune will decide in it's own good time WHEN the sync happens, not right away!

That used to be true. I don't know for sure when it changed, but I've noticed that Zune desktop opens up and starts to sync within 15 secs of me plugging in my phone to the wallcharger. I think it started this behavior when we got Mango.
