Some things I will miss is the pure Android experience No manufacturer or carrier bloatware. Also I will miss the quick OS updates from Google. Also I am going to miss updating over the air as opposed to Kies. I am looking forward to the top of the line specs of the SGS 5. Also the 1080 HD and Super Amoled screen will be awesome.... I have always liked the Amoled display better. Oh... and LTE. This will be my first experience with LTE. Also Corning Gorilla Glass 3 for the screen will be super. Seeing that this is my first Samsung Galaxy I don't mind at all that the 5 will be similar in appearance to past Galaxy S's.
