i keep mine in my right side front pocket by itself all the time. it's nekid, no screen protector or case.
I keep mine in my pocket (front right) and only have a screen cover on it. I have been thinking of getting a body cover for it, but holding out hope that Otterbox makes one for it down the road. I know it will add some bulk to the phone, but it looks like it would survive a good fall. My friend at works uses one on his iPhone and he takes his Mt. Biking with him.
i have screen protectors... but i have not put them on yet. and i keep my phone in my pocket. and i also have a body glove lol but i dont use it. and i have literally like no scratches or anything. i make sure i put nothing. literally nothing in my pocket with my droid. no change. no pencils. no keys. nothin. and i got 0 scratched (except when it has the occasional drop *soothes droid*)
I also put my m-droid in my pocket, havent had any trouble, don't use any protectors either. However I would like to find an arm strap for when I'm at the gym. The other day I was on the treadmill with my droid in one of the treadmill's holders ( I don't like having my phone bounce around in my pocket while i run). I accidentally clipped the headphone wire and sent my droid flying, bouncing off the conveyor belt and onto the floor. I was absolutely stunned that my droid didn't receive ANY damage, none. Even after falling on the floor which was made of concrete. Though I fully respect the ruggedness of my phone I'd rather not let that happen again.
For me, an $11 protector is cheap insurance.
To the OP: I carry mine in my front pocket with Seidio case all the time. Shirt pocket is preferred on the days when I wear a flannel shirt with a button flap to prevent it from sliding out if I lean over.
I carry mine in my front right pocket, which I think is less cumbersome than a holster would be. I place it screen out without anything else in that pocket. No screen protector.
