Is it worth it?

Not unless you like being really restricted in what you can have on it. Save up man, the bigger iPods are pretty sweet, what with all that wiggle room.

I got an 8g iPod just recently and I'm already feeling the pressure of the low memory. I only have 16 songs and 7 applications on it and it's already at 5g. Of course it did start at 6g. If you have the money to invest in a 32g, it would be worth it. But if you're not the type that would carry a lot of songs, videos, games, apps on it then you would really be wasting the extra space.

As for is it worth it to get an iTouch, I think it is. I've never had one or any decent smartphones, so I'm really satisfied with this.

16GB is proving to be enough for me. I put some music on there, and save the rest for apps and whatnot. I switch the music a lot, and for what I don't have on there, I rely on Pandora/last.fm/Spotify.

But yeah, don't waste money on 8GB. I bought an 8GB iPod Touch a few years ago, and hated myself for it later, barely enough memory.
