8. What's interesting [now] is that there is an emergent new model, and you
all are here because you are part of that new model. I don't think people
have really understood how big this opportunity really is. It starts with the
premise that the data services and architecture should be on servers.
We call it cloud computing – they should be in a "cloud" somewhere. And
that if you have the right kind of browser or the right kind of access, it
doesn't matter whether you have a PC or a Mac or a mobile phone or a
BlackBerry or what have you – or new devices still to be developed –
you can get access to the cloud. There are a number of companies that
have benefited from that. Obviously, Google, Yahoo!, eBay, Amazon
come to mind. The computation and the data and so forth are in the
servers.
