I've decided that I want to download some lectures from iTunes and another source to get some training that's available now for free. I have an iPad, but it's constantly being borrowed (I know you know why...). I was thinking that I could do what's needful with an iPod touch and do some Logos basics as well. My question is whether 16GB would be enough to do the job. It's not a big cost issue to go 32GB, but I'd rather use the difference for Logos purchases.
