The BrowserDeceptively powerful. Accelerated graphicsRich style and integrated virtual machine

The CloudYou have unlimited Virtual MachinesYou can write in any language

The BrowserYour user has a powerful Virtual Machine You can write JavaScript (or target it)

The user’s Virtual Machine is part of the cloud also…put it to work.
