This depends upon the size of games loaded/saved/installed in the 16 GB memory space.
8
About 7000000
about 3500 songs but im not sure
It depends how large the capacity of the MicroSD is! E.g: An 8GB MicroSd can only store half of a 16GB one and a quarter of a 32GB one.
yes 16GB is plenty of memory space for games music etc.
16GB it has a lot more memory, which helps it run faster with more games/apps.
3,500 songs, 20 hours of videos.
If you LOVE games then i would get 32GB. If your a texter not a gamer get unlimited texting (get 16GB).
Yes, you can.
A 16GB ipod can hold 3,600 songs
First of all, iPads come in 16GB, not MB. On a 16GB iPad, you could fit hundreds of apps.
There is no '4GB' iPad. The smallest size is a 16GB model. Every app is different in size, so there is no way of saying how many yours will hold. This question is similar to 'how many rocks fit in a 5 gallon drum?'
