I'd love to be able to upgrade my laptop RAM like that. Laptop CPU and motherboard manufacturers are still quite stingy about the maximum RAM they support. This limit is the only reason I had to buy a new laptop last year, and why I will likely need to buy another one in a few more years. A laptop sold today should support up to 2x64GB DDR3 RAM[1], but typical Ivy Bridge laptops only go up to 2x16GB, and a year ago it was max 2x4GB or for higher-end 2x8GB. The laptop I replaced had max total 3.2GB (you could put in 2x2GB DDR2 but the system would only see about 3.2GB, so I stuck to 2GB+1GB). Its 2007 Core 2 Duo is still blazingly fast, and its disk was easy to upgrade to an SSD.
