Recently, IBM has collaborated with Linux distributors such as Red Hat, Novell, and Ubuntu to launch a Microsoft-Free (not using Microsoft software) initiative. This involves pre-installing IBM's Lotus Foundations software on PCs equipped with Linux systems. The Lotus Foundations series is an all-in-one service solution that includes the Lotus Domino email and collaboration platform, file management, directory services, firewall, and office software. It is reported that IBM has reconfigured the Lotus Foundations software so that it can be pre-installed in Linux distributions like Red Hat, Ubuntu, and Suse. The goal is to enable desktop systems to operate without the need for Microsoft software. In fact, besides IBM, Google has also recently integrated its Google Gadgets along with its online document, calendar, and email software into the gOS 3 operating system. As advocates and pioneers of cloud computing, IBM and Google last year strongly promoted their online application software models, claiming that traditional desktop applications were outdated and that their online software had high download rates. So why are they returning to the desktop this year? What does this phenomenon imply?
