I do the same thing now! I used to be all about a cool ringtone, but now it just annoys me to no end. Vibrate is where its at. Although, sometimes people don't realize when I've just answered my phone and there is a couple seconRAB of confusion as to who I am talking to. If I ever use a ringer now, it's just the simple traditional phone ring.
Here is mine before I saw the light:
1) Bullet With Butterfly Wings - Smashing Pumpkins
2) Special - Mew
3) Sirius - Alan Parson Project (it made a cool ringtone...at least to me)
4) Disarm - Smashing Pumpkins
5) Dayvan Cowboy - BoarRAB of Canada (I really liked this one, but it was always too damn quiet)
