An 16Gb iPad can hold up to 199 app and 1 video and like 580 photo
3,500 songs, 20 hours of videos.
That depends on the apps. They vary greatly in size.
iPads are available in 3 memory sizes. All the memory is shared with apps, photos, videos and other data. Every CD is a different size, so it is impossible to say how many CDs your iPad will hold. If you just do music and a little gaming, buy a 16GB. If you want to do videos, buy a 32GB. If you want to do lots of everything, buy a 64GB.
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?'
8,000
It depends on how big the songs are... apple products only hold low quality MP3's anyway so most of them are 2.5 to 6 Mb so That should give you and average of about 4000 songs but if your into rock or metal closer to 2000 but if your into pop then probably 4500 songs :)
