Is cloud only for Business Entities?

It is an ambiguous issue, because, take an example of Windows SkyDrive, it is on a cloud platform, it offer 25GB of free space even to clients who use its services for free, YouSendIt.Com offer 2Gb for free, in both the cases there is a service for the client and also for the enterprises. However, the use of these are very customer psychically customized, like you cannot upload any file above 50MB into Yousendit, and you need to pay them for it, you cannot download it more than 100 times, the limitations are growing or in other words control strategies are increasing. Hence, we cannot say now itself if cloud is for individual people on internet or is it for entities looking for futurist benefits. However there is a growth in that area too likes TeamViewer services that are completely free with professional options.
