Yea 300$ more for a big ass 27" LCD, crushed into a all-in-one package.
You don't know what the HP Touchsmart is, do you?
"An all-in-one package."
Besides the way I see it, is if you get twice as much of something for cheaper (HDD, Ram, etc) in a pre-built system, you have to wonder bout the actual brand/quality of those components in order for HP or other companies to make a profit.
"Apple buys Samsung, Hynix and Micron RAM modules in bulk, just like good third party brands do, there is nothing special about Apple branded memory."
