It seem uncertainly for you 8gb itouch can hold apps programs.
Yes, that iTouch might not be compatible with all your apps.
It depends on what you mean by clone? If it is not an itouch, then you will not be able to use the apple apps.
There are two apps that I know of 'Peak' and 'Spark', but they are both paid apps and I think only work with iPhones and iTouch.
iTunes!
yes
can have about 60 apps in half a gigabyte
apps from an itouch, iphone, or ipad can very. check the app store to see all the apps
they are two different things! an itouch is basically everything that the iphone is without the phone. you can also install most of the apps that you can on an iphone on an itouch
Can you be more detailed in your question?
you get all apps free
You can Jailbreak your ipod and you get an app that lets you sort you apps/games.
