Is there any point in getting an iPad when I already own an iPod Touch?

I mean, he has not really been a big change in terms of functions in the new IPAD launched. Internet Apps Same features, same e-mail function, the same feature photos, movies, etc. Is this the same function, is not the only IPAD a bigger screen though? I’m pretty good with the small screen of my iPod Touch (with the exception of reading e-books). It has no meaning, more money is it all?
