Microsoft today is touting its latest round of Windows 7 offers, and this time around the theme is graduation and back-to-school. I guess it's never too early.

There are three big deals going on right now.

Sony VAIO E series laptop - This PC "comes loaded with Windows 7 Professional and a free Blu-ray disc drive upgrade starting at $799.99.  Plus, Sony will also give you a $90 credit towards the purchase of movies. The VAIO E series has a 15.5" screen that makes it easy to watch TV and movies, it weighs less than 6 pounds and you can get it in an array of colors so you stand out from the crowd." This deal is only available to US residents only through May 29, 2010.

$50 off when you purchase a Windows 7 notebook and a Windows 7 netbook from Amazon.com.  Buy two computers at Amazon.com and save some cash: "If you want to power through your homework with your PC and stay connected all day then a Notebook with Windows 7 Home Premium + a Windows 7 netbook is a great choice." This deal is also available only to US residents through May 29, 2010, but there are a number PCs to choose from.
