Alan is thinking about getting the Samsung Galaxy Note 4, but hears that it won't run 64 bit software. Leo says that really doesn't matter. All 64 bit can do is address more memory and handle larger chunks of data. But he doesn't really need 64 bit. Samsung is only doing this because Apple did it last year. There's no real benefit for a mobile phone right now. This is more likely the difference between the Xenos Opticore Processor (in Europe) and the Qualcomm Snapdragon (in the US).
