What I am asking out of pure curiosity is given the current official RAM limit for 2010 MBPs is 8GB (and thats what I got) if it can be pushed towards 16GB, the current max for laptops like HP envy etc. I read some folks have been successful in bringing the RAM upto 6GB on older 4GB max machines; hence the curiosity. I use VirtualBox VM for XP (2GB assigned) and Linux (2GB assigned), w/ Adobe Illustrator, Photoshop, Firefox, Thunderbird simultaneously. I know I'll better off running a proper desktop but I have to be on the move pretty often. P.S. I had been a linux user on a IBM T43p machine for the last 3yrs so don't flame me for mentioning HP Envy, it could well be any other brand that might support 8GB+ RAM.
