I've got a 160 GB IPod.
I know, I know. Apple = satan and all that, but it's rather convenient to have the entire music collection stored on one device with some extra space to spare.
I'm not an IFanatic, as such. But I also have an IPhone, and I find it rather handy.
My wife has the IRon, and I frequently get to borrow it since she refuses to iron my shirts. Another practical device, it must be said.
