It looks like email is working. I went cheap and didn't pay for the "migrate my stuff" plan.
Dragged and dropped all my email from one server to the other.
IM for Jabber seems to be working (so update to my email address if you regularly IM me via Gtalk, the other account I use can now go away).
All in all?
What is it missing?
It is badly missing:
1) Let me manage DNS
2) Google Groups (the current mail list bit is entirely ghetto).
3) Give me the bug system from code.google.com. Seriously....
Open issue? How can I syncronize my calander and my addressbook from my Mac....
Since I use procmail, I knew I would be recreating all my filters :)
