My friend used to have iPhone 4, she actually consider to go to iPhone 5. I went with her to Verizon store to check out iPhone 5 in person to see how it like. The first thing she said after few sec of playing with it, "That it? That all it have? What so special about it?" She wished that iPhone 5 should be a major leap in technology and it didn't feel that way. Even she claimed it S3 and Galaxy Nexus is far better than iPhone 5. She from a strong mac family, she decided to go to Note 2 and really love how it work. A first Android user in her family, she love Google Play, she kept renting and owning a few movie from Google Play and it look fantastic playing on the screen. And she love Google Navigation, she was worried that it would use up so much data for using Google Navigation but amazed that it only used 10 MB in two hours round trip in data usage.
My other friend is on the same boat. He is the early adaptor of G1, he went to iPhone 3s after that. He said he like both OS and they work well. Then went to Thunderbolt then year later went to Droid Charge for free from insurance due to Thunderbolt kept having problem connecting to LTE network. It just couldn't stay on LTE network longer than a min. Anyway he did consider to go back to iPhone ecosystem because he miss it. After looking around iPhone 5, he made the same remark as my other friends and decided on getting Note 2 next month.
