IPod Classic vs IPod Touch? Need help with purchase. (Details below).

I’ve been using an IPod Classic with only 8 GB. It lasted a long time and finally bit the dust. I need to replace it. I use it a lot. I need something with a lot of memory because I download a lot of non-music MP3’s (audiobooks, or long radio shows). I don’t like having to go into ITunes, uncheck items and then add more because the memory isn’t enough. I wanted to get another IPod Classic with 160 GB…but a friend of mine swears by the IPod Touch and thinks I should consider one. She raved about the “apps” and how it was just superior, etc.

Knowing that the above is what I use it for…..and that I need a great deal of memory….can you tell me what the advantages/disadvantages of both are? The IPod Touch has up to 64 GB memory…is that enough? Do I need the extra bells and whistles that an IPod Touch would give me?

Sorry for the geeky non-tech explanation…red face

Any thoughts would be appreciated. Thank you!
