Well, my gear is as follows, prioritized by order of most frequent use:
1) Canon HV20 for video recording and some stills.
2) Canon EOS Digital Rebel (the original 6 MP one) which won't be replaced until there's a new lens mount.
3) Canon PowerShot S500 as something small to take with me for better pictures than the HV20 can take, though it isn't used a lot.
4) My iPhone's camera... listed for the sole purpose of it being a last resort if I don't have anything else on me.
