Music cell phones do have a few limitations you should keep in mind. First, the most important is that the amount of integrated memory on even the most feature-rich multimedia handsets tops out at a few hundred megabytes. While the phones usually offer expandable memory card slots as well, the storage space won't be anywhere near that of an 80GB iPod. Second, the interface on music cell phones tends to be a bit rudimentary, and the navigation controls will be different from handset to handset. So, if you're an iPod purist who relishes the click wheel, you'll have to get acclimated to something less sophisticated. And because a carrier is involved, music cell phones typically come with a load of restrictions you won't find on a standalone music player. This is particularly true regarding how you get music on the phone. Also, though carriers such as Sprint and Verizon have their own music stores, they're quite pricey.
