If Mac OS X 10.6, Snow Leopard will be shipping in September then the earlier the better. The arrival of Windows 7 will come on October 22nd. Likely less than a month after Snow Leopard, Windows 7 is what many companies have been waiting for to get migration projects lit up. While there are a number of new features, few are more important to companies than the fact that it is very capable of running on new or old hardware alike. Windows 7 adoption shouldn’t stop you from buying now though, if you’re in the market for a new machine. Microsoft announced that it will include a Windows Upgrade Option for new machines sold until that time, where they will provide free upgrade licensing from Vista to Windows 7.
