iTunes is the application on a pc or macintosh computer. The iPad has a special USB cable to connect. Before I go any further i do not think you understand the concept of the iPad as apposed to say a typical pc. The apps are very small I have over 100 installed on a 32gb iPad plus i have 20 movies not to mention close to over 1000 pictures and some 1500 songs. Their is no hard drive as one has on a pc it is solid state and up to 64 gb in size. Every thing is on demand that is instant on no wait. With wifi i am from start up of safari on the Internet in a few seconds. One currently needs a pc or mac to back up and synced music . I suggest that you should go to an apple store yourself and do abit of research about the iPad then i know you will have a clearer picture. The iPad storage is more than enough for 90% of users. It is more about management using iTunes .
