The problem is phones wouldn't need 2GB of RAM anytime soon if Google would optimize the Android OS.
I have the Bionic, and while I am by no means someone who downloads hundreds of app or has dozens of widgets running (I have maybe 5 widgets running) it seems I have 650MB of 1GB RAM used.
The main reason for this is the ridiculous amounts of programs Android will just start that I never started. Anytime there is a data drop, Play Market, GMail, Slacker, Music, G+ and several other apps start by themselves. The email will also automatically check itself though I have it set for Manual in the settings. There is just no good reason why all these apps need to start up by themselves. Many I don't even use, but can't uninstall unless I root which takes me off the OTA path if I do uninstall the apps.
Many people say "Well Android will free up memory by closing apps". This is true, but the problem is it doesn't shut down apps that aren't wanted. The first thing it will shut down is the launcher replacement. Obviously I want that running, so by closing it, this automatic clearing of memory is more of a hassle.
It's also ridiculous apps don't all have Exit buttons. I know it can be done, Tunein and Weather Channel have them, as does a couple other apps. When I hit Exit, those programs close and stay closed until I want them open. Opening these apps doesn't take any longer to bring them up than it does an app already loaded into memory, at least not any longer that is noticeable. It's ridiculous my phone uses almost as much memory as my Windows desktop.
Perhaps if Android didn't think it knew better than me how I want to use my phone, it wouldn't need so much RAM, at least not anytime soon.
