on the iphone (here i go again), the power button would also silence a ringer w/ 1 press, and a second press would send the call to voicemail. Worked great when i was at work and couldnt answer the phone, i could at least shut off the ringer but just hitting that button while still in my pocket. W/ the droid, i actually have to take the phone out to silence the call, thus the customer realizes im paying attention my phone, not them. thankfully ive been getting the quiet ringer lately , so at least that helps
