Windows 7

When Microsoft released its new operating system Vista, it met a storm of resistance, which generally boiled down to two big problems - it required a very fast computer and scads of memory to run all the features, which for a lot of people would have meant a serious upgrade of their computer; and there were a lot of incompatibilities with existing hardware, eg printers, modems, sound and video cards, etc. While most of the incompatibilities have since been sorted out, the memory problem is still a major one. Hence, a high proportion of XP users are clinging desperately to their operating system. So much so, that Microsoft was forced to extend the length of time it would support XP. Vista still has not attracted the user base that Microsoft was expecting, and the ongoing problems forced it to hasten development of a replacement operating system, dubbed Windows 7. Development of this is well advanced, and several million people downloaded a free trial (called a "beta"), which has generally attracted good reviews. As Pat Pilcher wrote in the NZ Herald:

Having used Windows 7 Beta for the better part of two weeks, I'm pleased to report it takes Vista's strengths and manages to fix most of its annoyances. I'd even go as far as saying that Windows 7 is perhaps one of the most complete and bomb-proof betas I've ever used.

It looks like a lot of people will leapfrog Vista, and hang on to XP until they can upgrade to Windows 7 when it is finally released (and I will almost certainly be one of them, unless I have already ditched Microsoft completely and switched to Linux, which I am more tempted to do by the day).
