motorola Q

My new Motorola Q phone is active. It's decent - but the one thing I would have liked (as compared to a Treo 650) is a button to switch between silent and normal mode. So many times, I am in a meeting and want to switch to slilent/vibrate mode - and have to look at the phone and select the options. Treo was nice - it had a simple button - without looking - I could change modes. Yet to try out various functions. Our company has Good messaging deployed and this is a battery hog. Luckily the phone has a USB charger so I can charge it anywhere.
