Windows 7 has started a trend of allowing the Beta versions to run for at least 1 year so that they can produce an issue less Operating system. This approach is very much successful so far and hopefully every company should follow this trend. The first service pack of windows 7 will be available in the first month of 2011 or may be till the end of 3^rd month.

This release is quite late but that OS will be trust worthy and user can use it with a doubtless mind. It will be fun till the release of SP1 as the dates will change every now and then.
