Motorola Q

I have read all of the posts and the answer is still not completely clear. I currently have a Blackberry 7750 and use the blackberry web client to push my pop3 email account. Can you get true "push email" with the Q for a pop3 account through some type of web client or does it only work on exchange server or other email server? Does anyone know if Good runs a web client or does their software only run on an email server? On a separate note, does anyone know if the Q can be tethered as a modem like the Blackberry 7130e?
