The iPod touch, in my view, is very bad. I still have one though. Basically, I think on this page is where I talked about my experiences with difficulty in filtration:

Basically, if you don't have one, then you really don't need one. If you need to check your email, you can do that on a computer. If you need a camera, there are plenty available for cheap. If you need the shas in your pocket...well, at first you think "I'm going to be using my iPod for Torah!" and then it quickly goes down, down, downhill from there.
DON'T GET IT. Even if you don't fall because of it, it's huge huge huge bittul zman and is pretty addicting; also, it can be difficult to filter.
Please, for my sake, return it as soon as it comes. You've lived without it for so long, you really don't need one, and it will cause more damage than any good it might do.
