At the current moment, 1GB of RAM on ICS is not enough. Whether that changes with the Jelly Bean update, remains to be seen, but I just find it frustrating. I understand the change between CPU chips in different countries, but RAM? Clearly Samsung feels 2GB is needed for optimum performance, as they released variants with that amount in it, but why should those with 1GB suffer in the meanwhile? I'm really upset. Switching back from a "heavier" application to the home screen results in a slow loading of icons and widgets. Sometimes the music player playing in the background just closes because of low RAM. If Jelly Bean solves these problems by being more efficient, that's good, but in the future, when a new version comes out that needs more RAM, 1GB RAM variants will suffer dearly, while 2GB variants might not. Either we all suffer, or we all don't. Not one group will while another won't. Very unfair. What do you guys think?
