I've been using Yahoo finance for years. The thing I don't like about it is the stock charts. The chart is not very visually appealing. Remember when google finance had their charts. I always used their's over the yahoo one. I don't like that it's a strip and not the full screen. Finviz and barcharts also have nicer looking charts.

I agree, Google had terrific charting, but this is great when I am in public and don't want to open my investment account.
