The big problem with portable computing devices is that they're portable. What I mean by that is this statement is that these expensive devices are put through a lot of wear and tear, and sustain damage just from being toted around. Many people's cell phones perform many functions at once: cell phone, email client, MP3 player, and even portable game device . As such, these portable gadgets are mixed in with other items in a bag (or purse), and can easily get scratched or dented. Add into the mix that many new gadgets have delicate touch screens, and you can see why there's a great need for excellent protection.
