No
Sometimes depends if the apps that you install have bugs
You cannot make your apps transparent. Yes you can |:/
because there are a lot more ipod touch apps than the regular ipod games and apple doesnt make all the apps but they have to put more effort into the ipod games than the ipod touch/iphone apps.
an ipod is very similar to an iphone, just cheaper. you can get apps for an ipod that make it do the same as an iphone
You cannot make iPod apps directly from your iPod Touch. Apple does allow you to buy a software so you can create an app. There are two software types, one that is more advanced than the other, and both cost hundreds of dollars each.
You probably need to make a itunes account
if you click restore ipod it says do you want to make backup for this ipod same with updating it asks the same thing! by the way a backup is saving everything on the ipod.
That's probably because someone put restrictions on your iPod touch to make it so that you can only download apps not 17+.
No, the apps for iPad are much bigger rather than compressed like the iPod touch apps. For example, just as you would enlarge and slightly distort an iPod touch app on an iPad, you would have to compress and make smaller an iPad app for the iPod touch witch is virtually impossible
there are a few voip apps that can be used to make calls
do surveys/download apps like shopkick/apptrailers
some apps will make it so to access stuff on the free app you have to pay but most free apps will not charge you at all
