I just came across this and am intrigued. I have long practiced safe-surfing -- always use a VPN for example -- I pay to have a private IP address all to myself, etc. This seems to take privacy and security to a new level. The sites you visit are opened in the cloud and the program shows you the result. The actual files, images, flash pop-ups, etc., never reach your machine. This is a paradigm shift.

The first drawback I've found is the windows you open close after 10 minutes (and are vapourized!) unless you click for a 10-minute extension (which seems to be repeatable). I guess this keeps people from tying up their resources. It also offers 'hands-off' email and file management, making the threat of malware and viruses less an issue.

I'd appreciate any feedback from people who are familiar with it.
