But I'd say that 6GB is probably more than adequate for casual users for the next few years. (4GB might be enough, but if we allow for crapware...) 6GB isn't top of the line, though; 8GB laptops are fairly common, and even higher capacities (i.e. 12 and 16GB) are available. I am hard pressed to exceed 6GB of memory use without resorting to methods like booting a virtual machine.
