With IMAP, the emails still get downloaded to your email client so you can view then offline. The only difference is there is a 'sync' process everytime you check mail so it matches all your other email clients. That's why it's a step up over POP.
Since I use .mac's other features, I'll continue to use .mac mail. I forward all my emails from gmail to mac mail. This way gmail acts as a backup service that has a copy of all my emails (and it's a great spam filter too!).
