This is one area that Windows Mobile shines. OTA syncing with Exchange
over HTTP. You can even do quasi-push email by having the phone keep
it's HTTP connection open for a long time, and if there is new mail that
shows up while the connection is open, the server sends it on down to
the phone.
Even Palm OS type devices support OTA syncing with Exchange, although in
slightly crappier form.
