Heidi-
Thanks for asking this question as I was wondering about apps myself.
My 1st generation classic iPod just died over the weekend and I picked up the 3rd generation 32 gig iPod Touch yesterday. I now have serious iPhone envy as they say the Touch is an iPhone without calling capabilities. I got all the artwork downloaded for my albums....so cool, set up email and got online. I'm still getting used to the keyboard and keep hitting the wrong letters but I'm sure it just takes practice.
One question....do you know how to change the weather location so when you touch that icon it displays the weather info for your area? Mine shows NY and some other country I've never heard of

I can't figure out how to do it.
Enjoy your new toy!
