Rouster is a credit card sized personal computer powered by a subscription cloud service. It works with ever growing number of shells to turn it into any device one can imagine: laptop, desktop, tablet, game console, etc. This way we can reduce the overall price of any personal computing device by up to 70% and spread it across its lifetime. Rousters have longer lifespan since they don’t need physical upgrades and users can increase their computing power at any time. Having the entire computer on the cloud is safer, more reliable and above all-allow users to retain their files and applications across devices.
