gmail is good, just takes a little getting used to at first, esp if you are used to the Outlook setup.
Example - they call your emails 'conversations' so when you reply to an email, it's now a conversation. If you delete that email from the sent mail folder, it could also be deleted from the inbox as well b/c it's 'one' conversation.
It's not bad, just have to get used the setup.
The nice thing is how much other stuff is integrated as well - google calendars are incredible if you need an online calendar that others can view and/or add to it. You can make your calendar public or private and invite certain people to be able to see it. Works great here around the house coordinating schedules now.
