Came across this great app : Life2Go for your iPod. It can store info about things you need daily like: Gas prices within your zipcode, Movies playing near you, Weather, your customized News feeds from your favorite newspapers, Driving Directions to interesting places you want to visit etc.
You can also store lyrics for all the songs in your iPod and sync them automatically. What’s more, you can backup important files from your Mac/Windows desktop onto your iPod easily and automatically. It costs only $13 and has a trial version for checking it out. I am trying the demo version and liking it immensely. This is a definite buy ! I like the fact that it’s available for Mac and Widows platforms. I give it 4 stars!
