In the fall of 2007 I was thrilled when Google enabled IMAP for Gmail, but I also thought they were crazy. Who would use the web interface (and see ads) if they could get synced mail in a rich desktop client? Turns out that if you make your webapp better than anything on the desktop, people will use it. Less than two years later, I’m using Gmail’s web client exclusively, mostly thanks to Gmail Labs. For the July issue of Macworld, I ran down my favorite Gmail power tools, in and out of the web interface. Google moves so fast with this stuff that between the time I turned in this copy and it got published, two more new Labs features were released that have made their way into my heart: Sender Timezone and Inbox Preview. Love it when good software is a moving target.
