[Novalug] Laptop ram: 8 GB?

I concur. My current desktop came with 4GB and two empty sockets. I immediately upped it to 12GB. I'm also running multiple VMs, browsers (which are bigger pigs than the VMs!), and do photo editing. With 12GB it is rare that I swap, but not unheard of. If I only had 4GB of RAM, memory would be better measured in RPMs, not nanoseconds.
My current laptop is 5 years old, and only supports 3GB of RAM. (Yes, it's maxed out.) I can run 1 VM on it, if I am careful to keep its memory footprint small.
My next laptop will have 8GB of RAM or more.
