Gmail stacked cards UI

Google continues to rapidly reincarnate their iPad Gmail web app, this time introducing Apple Mail-style stacks into the mix. Back when the iPad optimized version of Gmail was launched, Google emphasized their new code base would allow for just this kind of fast feature development, and now hot on the heels of the new compose screen, stacks will allow for easier grouping and organizing of mail. They also gave Google's team a chance to play with CSS transitions to try and get closer in look and feel to native apps.

Our question is -- how many of you are using Gmail via the web browser on iPad rather than via GoogleSync or IMAP in the native mail app? Are the extra features like labels and star worth the lack of notification and native performance?
