Future of computing?

As I type this from my 8 year old laptop, used solely for accessing the internet. I came across something this evening make good sense to me nivio.com. Nivio brings the power of a desktop to the internet. Think about it... Going to a friends house, the locale library, a kiosk at the mall and accessing you computer and not having to worry about opening network ports, viruses or hackers getting into you network. Just go online anywhere and access your desktop. They provide most of the everyday applications like Microsoft Office, IMs and image editing for about $5 per month. Not bad when you think about the price of Microsoft Office. That would pay for several years of this service. This would be a rebirth of the dumb terminal. Remember those? With the speed of the internet and public computers showing up everywhere, like McDonald's, this could be the future of computing for the typical user.
