We really like the Live Chat helpdesk idea in general and are glad to see Apple jumping on the bandwagon here. When done correctly and scaled reasonably, it allows a much better experience than talking on the phone. It is also a lot easier to cut and paste from a chat than from a phone conversation.
Hopefully, you won’t need it but it is there when you do…
Apple’s site says:
We’re pleased to announce that English language Live Chat support is now available 24 hours a day, seven days a week. If you encounter an issue while using MobileMe and would like to address it immediately, simply go to MobileMe support. Click on the topics at the bottom left of the page to see if your question has already been answered. If it’s not, click the Chat Now button to initiate a realtime help session with a MobileMe support agent.
