Brainwashed?? Umm.. no. All one has to do is have a quick look in the Activity Monitor in OS X to see how much of a memory hog the OS and other apps are. I dare you to not go crazy while trying to run any recent model Mac on only 256MB ram.As a software developer I can tell you 256 mb is plenty of room. People have been brainwashed into thinking they need 2Gb to run an OS or any decent program.
The XBOX ran on 64mb of memory and that has much higher resource requirements then multitasking a couple simple apps. The BIG nintendo DS games use 128mb of space total, most are only 8-16mb in size.
It's all about the quality of code thats put out there. Multitasking pandora, aim and skype are no brainers given they don't need much.
And Skype? That thing is a huge resource hog in OS X. Try running video... tell me how long it takes before your fans kick into overdrive.
People can't help it but to think they need more ram, since the only experiences we've got are from using our computers. It's true if the code is clean and efficient the apps can run better, but try telling that to the thousands of developers who write sloppy code.
