Depends on what your interests are. There are all kinds of apps out there.
All iPod apps are from iTunes.
Nope, no sharing apps.
no you cannot use ipod and iphone apps on itunes, but you can buy the apps on itunes and put them on your ipod and iphone
The apps should not disappear from your iTunes account.
yes you can ... on the itunes appstore... and also check out the iappworld.net if you want good apps and games just for freee .... :)
An example of a good platform for downloading apps is Google Play Store and iTunes.
you can search any apps on iTunes or see apps on the home page on iTunes
itunes is a good start=) you can also get free apps
No, you just need to free download iTunes and then use it to buy apps. iTunes is free.
They shouldn't be; apps are tied to the device and the Apple account, rather than iTunes.
You buy apps at itunes.
You can but I don't recommend it, because you won't be able to have apps from multiple itunes acct and you have to make a new account, to download the apps.
