I would like to see future revisions of the iPhone include a
MicroSD slot or release one greater than 10gigs. The
ultimate appeal of the iPhone is a single device that
replaces my iPod and Smartphone. 4gigs definitely won't
cut it, 8gigs isn't enough. 10gigs is the minimum and
greater than 40 gigs is ideal. For me, the storage
requirements are mostly for storing 90% podcasts (some
video) and 10% music. If a 40gig iPhone is not possible for
the next revision, I would like to see a software update
that would allow the phone to stream podcasts, thereby not
requiring the additional space.
