How Do You Use Your BlackBerry Series: Holster or No Holster?

The next stop in our ultimate pursuit of knowledge brings us to the age old question: do you use a holster for your BlackBerry? Personally I've never been a big fan of holsters for my device. Sure its convenient, but I'd much rather just hold onto my device or put it in my pocket than tote it around on my belt. There are benefits to using a holster, among which are keeping the device secure as well as being able to set separate profiles (which can come in handy), which to some I'm sure are a big draw. However I think most people prefer the "naked" approach or just go with a simple case on their device sans-holster. So our question this week is: Do you use a holster for your BlackBerry? This only counts for the official BlackBerry holsters or another type of belt-clip holster like the ones that come with the OtterBox Defender. If you use just a case on your device, then go with no for your answer on this one (we'll save that for another poll). Be sure to leave a comment letting us know why you do or don't use a holster as well.
