I hope Google never forces users to switch to their "new look." I like it for their other services (Docs, Search), but for mail it looks so dull for some reason

I hope Google never forces users to switch to their "new look." I like it for their other services (Docs, Search), but for mail it looks so dull for some reason. Perhaps I'm also just really used to the "arcade" theme I've been using for 2 or 3 years. Regardless, a mobile app will be nice to have since it will be optimized for Gmail (which is all I use, even for my own SMTP). I do get push notifications through the standard Mail app, though, so I'm not sure why that was a complaint.
