Who made the decision that we should upgrade our operating system every few years? Computing technology doesn't change too much and, in theory, Windows XP is a strong, solid and reliable operating system which, with the right drivers, will support even the latest hardware. When Vista was released, it caused businesses to upgrade their software to 'support' the latest operating system. There shouldn't be a situation where an operating system dictates the software you can use and install. However, Vista does have some benefits and one of these is the improved user-interface.13 Feb 2009
