PROBLEMS WITH WINDOWS VISTA
About half of the existing PCs won't be able to take advantage of the "Aero Glass" compositor found within Microsoft's upcoming Vista software, due at the end of this year. That's okay. Wisdom dictates that one not mess with Windows. IOW, the rule of thumb I follow with these things is that it doesn't make sense to really screw up an already iffy Windows environment by trying to upgrade to a new version. Just wait until you get your next computer. By then all the major bugs will be worked out and you won't have the stability and compatibility issues of an upgrade.
