The good:
- more space (16GB vs my old 8GB iPod)--more music available to me, space for all photos, and room to grow
- more features (the biggie: constant connectivity via the network; slightly lower down the list: a better camera, and more newer apps available to me)
- combining my music player with my phone (not trivial; I've missed plenty of calls in the past by not being able to hear my phone due to headphones and music via my iPod--now, of course, my phone is my iPod)
The bad:
- its a slippery little devil (this has been a pox on the iPhone from its first incarnation, and it hasn't changed yet--purposefully, of course, in order to prop up the secondary market for accessories like cases)
- a more baffling interface (iOS 7 is not as user friendly as the earlier operating systems; at first I found using it confusing and non-intuitive, plus the visual design is not as friendly and inviting)
- loss of some settings/data (several of my apps did not transfer their data; I had to restore some from backups, and others needed direct input of info; plus using iCloud [since disabled] killed some features like syncing my contacts directly--not good)
But, as with the ACA, among other things, I'm sure this is a thing that will iron itself out with time. I'm happy to have joined the 21st century (or at least its second decade) with my communications device, at last. I gratefully accept your congratulations. Selah.
