Really, the one thing that I don't like about the iphone is that I have to spend $300 to get 32 gigs of memory, and there is no microSD slot. I don't have an enormous catalog of music, but I fill up a 16 gig phone as soon as I plug it in. It's nice to be able to have everything on the device. I would think that in the near future they would start phasing out the 8 and 16 gig entry models, but I suppose there are lots of people who don't mind the small amount of space.
I wish I could test drive both phones for a week or so before committing, but unfortunately it doesn't work that way. How well does the Samsung function with itunes and managing music and podcasts?
iTunes and the GS3 do not work well together at all. You can download an app that will transfer your iTunes library to your GS3, but for simply working out of iTunes the iPhone is the way to go.
I'm with you on the 32gb memory stance. I am very glad the GS3 has microSD, as I have already filled it up with music. If you don't mind me asking, who is your provider?
