I wonder if the people who talk about 1GB of ram in a tablet really know what they are or aren't gaining.
iOS doesn't need much ram to run smooth. In fact, tasks like HD video, surfing the net, viewing images, streaming content, etc. are much more streamlined and fast on an iPad with 256mb of ram than it was on my old HP netbook with 4GB ram.
It isn't always about ram folks. If iOS were to integrate MORE then obviously more ram would be needed, but why spend more in adding ram, increasing the price of a device, if there is little boost?
I suspect Apple is adding in enough ram in order to maximize the potential of what the iPad has to offer
Just like megapixels in a camera or Hz in a tv - it's all just marketing.
My macbook air with a solid state drive and 2GB of ram performs SOME tasks faster than my mac pro with 12GB of ram. Like opening programs, files, etc.
So though RAM is important, it's not the end all be all.
If we talk true multi tasking - that's a different story.
