Wow, yeah. No one who actually uses OWA on a regular basis could say that with a straight face. Gmail was far superior, right from launch (or at least as close to launch as I got an invite).
You can actually use your gmail account to check your exchange accounts. If your work place allows that, go right ahead! I've been accessing my univ exchange account via gmail and never regretted it.
Even according to the standards of marketers/evengelists, this is so overboard.
