You are just flat out wrong. There isn't enough available RAM that the second you try to multitasking it wants to kill the app you are using.

Rofl. Okay bro if you even read what I typed out you wouldn't of said that. Even when you multitask the android OS will still close down the app that isn't active and is running in the back round. On Froyo and above I have yet to see people have apps FC cause of "low RAM" my friend at work is a perfect example. He has only has a 1/2 gig as well and he launches app after app after app, and everything runs fine on his phone. No FC's no real slow down, like I said if you know how the Android OS manages memory, you would know its not a bottle neck. :icon_ banana:<--- banana for you enjoy.

That is a small article basically stating the same thing I have been.
Say you listening to music and browsing the web. The browser is the foreground app so if android needs RAM it will close the music app if there is nothing left to close. The reason 512gb is enough on single core phones and not dual core OS because more RAM has to be dedicated to the dual core processor and is not accessible by the OS. This is why you are seeing tablets with 1gb of RAM even though that much RAM is extremely taxing on the relatively small batteries. Can't really be any clearer than this. By the way, I am an electrical engineer who designs these things for a living.

Good for you bro. I do everything you're stating in your above statement at the same time. Surfing web listening to music and I've never had any FC's. I'm happy w/ the performance I get from this phone, and see no reason for anything over half a gig of RAM for the time being. Yes when the software advances, then more RAM probably will be needed. But for the time being 512 is more than enough. Ofc tablets will have more seeing that people tend to do more at once on a tablet ie more workspace than their phone. Remember the keypoint smartphone = phone in the end. Manufacturers are obviously still producing their devices with only half a gig of RAM? Why? Because it works, that + battery savings in a world where battery tech is far behind. I have never had a single FC and I'm very demanding on my phone, I run app after app while surfing, while streaming pandora, and have never seen any slow down. RAM generally is the last thing when it comes to bottle necking with the Android OS.
