For those of you that carry around a cell phone and an iPod touch on a daily basis, how do you manage this? Does it get irritating after a while? I have a PDA smartphone and just got a touch today, but it seems like it might get annoying walking around with the cell in the left pocket and the touch in the right all the time. I planned on waiting until the iPhone gets 3G to pick one up, but I may go grab one if it turns out to be too much of a hassle worrying two devices.
