Trading and investing in the cloud

I don't know if you remember, but when Internet banking first appeared you had to install your bank's client software onto your PC from the CD that they supplied. If memory serves me correctly -- hey, it was little more than a decade ago -- the same was true of dealing in stocks using stockbrokers like Charles Schwab. Now you just do it all via the web browser, and it doesn't even have to be a web browser on your PC.
