Microsoft’s target for the release of Windows 7 shall be anytime late 2009. That’s almost 3 years after the release of their current operating system “Vista”.
Windows 7 is equipped with new features such as support for touchscreen, faster SSD read/write, improved taskbar and most of all – better hardware support that doesn’t require you to upgrade if you are already running Vista.
Your laptop will benefit from the upgrade too since Microsoft promise that Windows 7 will consume less power for around 10%.
