Right... I think thats a good point, there's certainly nothing wrong with anyone spending the extra money for the extra ram, or storage, or whatever, but for most people it's probably a poor investment. I could see how for some being able to have 50 applications all idling in the background with immediate access is nice, possibly even important to them... but does the typical user function in that way? Doubt it. I would imagine the typical user has a handful of apps the switch back and forth to.
Safari, Instagram, Facebook, Twitter and Netflix is probably your base.
To anyone who wants it, I'm glad it's available, but from a value proposition it's difficult to most to justify.
