The biggest economies on the foreseeable future are going to be in Asia, South America, probably Russia and some parts of Africa. Does anybody think that the infrastructure will permit any time soon cloud computing in those areas? An then take US and Western/North Europe. Cloud computing in small businesses in Kentuky or rural Dakotas? or even in parts of France, UK or even Germany not to mention Poland (!). You see not every country is Sweden or Finland when it comew to Internet infrastructure and usage. Then take businesses by size. Does anybody think thta giants like General Motors or other great companies will move to cloud computing? Not likely. Then who is going to move into cloud computing? Probably the small to medium-small businesses in US part where the Internet is properly working (when it works) or parts of UK. OK, let them have it. We are going to have the same situation with the one that developed in the late '80s early '90s when some "IT prophets" announced the death of the Mainframe, because "we had the PCs now!". Less than 15 years later tha Mainframes (smaller in size but thousand of times more powerfull) came back triumphantly! Who is going to deploy web-apps without a mainframe? Well, I say Deja vu!
