The iPod Touch is much more than just an MP3 player. You can also watch videos, search the web, send text messages via wifi and much much more. The apps that are available for the iPod touch are infinite and range from silly time wasters to professional tools for your job. Nurses have greatly benefited from apps for the device. I have owned other PDAs and pocket computers and I have a state of the art tablet laptop and a touchscreen all-in-one desktop and the iPod Touch is my favorite out of all of these. It is sleek and thin and very durable.I have dropped mine at least three dozen times and it still keeps on ticking. I just wish they had these things when I was in college or when I was a kid. I use it all of the time to check the weather, check my email, Facebook, Twitter, play games and even text. Once again, the iPod Touch is the greatest invention ever as far as gadgets go.
