Yeah, Google Finance does have a list of stocks you can add to your portfolio, and I believe you can synch with what you bought for and how much. The best part is that for your portfolio, there is a tab that will display all the top stories related to your holdings too. I also love the sector summary and the trends just to keep an eye on how things are going over the entire market to get a good story. Google's articles are all found autonomously using software that searches the net's main websites to gather info and is sorted based on popularity or something like that so you get a good idea of whats going on. They display stories without redundant stories, again all programmed in autonomously; and if you want to read more, of coarse there is related articles.
One of my friends works for Google finance, doing the front end development - the graphs and data in particular. So I have a bias toward google.
