Hi guys I want to buy an HP Mini 311 shown below. I want to upgrade the ram, but am confused. It says it includes 1 GB of RAM with a maximum of 3 GBs. Does this mean there is 1 GB built in and the only way to upgrade is to buy a stick of 2 GB DDR3 laptop RAM? Thanks. http://www.shopping.hp.com/webapp/s...category=notebooks&series_name=mini311_series -Is there a big difference between the Intel Atom N270 and 280 processor? Some people when I search through google say yes, the others say no. -Is the Intel Atom powerful enough for internet usage, word documents, and Hulu fullscreen?
