Does the Droid have Push for POP3 accounts?
Android is a mostly mature platform now, everything the other mobile devices can do, it can do (better).
It can view .pdf's, it can open and save attachments, it can do POP, IMAP, SMTP, Secure email, etc.
It can be setup EXACTLY like your current "push" email phone like a Blackberry or a Windows Mobile phone. I have a Hero right now, email comes to it before it even shows up in my Gmail inbox! Your work email *MAY* fall back on "polling" if the server doesn't support "IMAP Idle." Polling just means Android will check the server for messages every X minutes rather than the server sending messages directly to the phone (push).
Android comes with two email clients--Gmail and Mail. The Gmail client allows you to use ANY Google (or Google Apps) email account. This simplifies some things and allows you to sync you contacts, calendars, tasks, etc with the Google servers (cloud). The Mail app is like any other mobile email application. You can setup POP3, IMAP, etc with it. It works just like any other modern mobile email application. It can either pull (poll for mail every X minutes, some believe this drains battery faster) or push (has an always open connection with the email server, when the server gets a new message, it "pushes" it out to any connected device).
Simply put, anything your Blackberry, Windows Mobile, or even that "media"/dumbphone can do, the Android operating system can do. And yes, that $30/month data plan is REQUIRED if you're sticking with Verizon. NO EXCEPTIONS!
I also ready that you can sync it to exchange and the emails will be pushed instantly. My question would be does that include users of Outlook without exchange?
