IPod touch or just extended memory for my smartphone?

I have an iPod just of music because the battery life of my phone will die with all the times I listen to music and go online and all the other stuff I do. I would get an iPod touch just for music. I also like the layout of the iPod music. But the speakers are quieter on the iPod than on the phone so why not have both and listen mainly on your iPod via headphones or earphones and phone wjn you want to blast it out loud.

It really comes down to whether you think your use of then phone for stuff your do on the iPod would be so great that you'd use up the battery for on phone things. The iPod is otherwise almost completely redundant with your phone such that you'd be out at least $200 for something that does what your phone already does. the advantage of phones that support microSD cards is that they have no practical memory limit - you can always swap one card for another. If your phone dies the card can always be put in another phone. If the iPod dies and you haven't saved its stuff by then then it's lost.
