I knocked down the rating because of the purchasing experience at Walmart. I am sure it would have been much smoother had I bought it on the Apple site for pickup at the Apple store 20 miles away.
This is a fantastic gadget. I bought it partly for the camera, which I just now used on a 3 day trip with great results. I also wanted better speed than my iPhone 4, which I'm keeping, because it has Verizon as a carrier through walmart's Straight Talk prepaid service (you have to use AT&T with the new iPhones if you want the straight talk service). This device leaves the iPhone 4 in the dust for speed, and has 32 instead of 8 gig RAM.
I enabled a setting on my old iPhone 4 and now can use this iPod for messaging as long as I'm on wifi.
The purchasing experience was something else. The Walmart site was very difficult to use in purchasing this device for store pickup. Once I picked it up and got home with it, I found pictures and account information from another person. I made another trip to exchange it without further incident.
TIP: Configure your apple gadget at the store before taking it home, to be sure it's not a used return.
