ipod Touch - Can anyone give me a reason not to buy this?

[X Factor]

I honestly don't see a need for more than 10 gigs of music. 10 gigs is such a huge play list anything more gets to be a pain to shuffle through.

Video of course is nice to have... but I think 16gig will suffice for me. Being that my current mp3 player (my blackberry) has 1 gig.
