Just in time for summer weekend reading, Microsoft today filed its annual report for the 2007 fiscal year, which ended June 30.

Some interesting things to note within the first few pages:

Microsoft's stock buyback plan reduced the number of outstanding shares by about 600 million, to 9,375,492,496.

This year's shareholder meeting will be Nov. 13, a Tuesday.

In the section describing Microsoft's mission in general, there's a subtle change in language from last year with regard to the company's investment in long-term growth, a big theme of last week's Financial Analyst Meeting.

Last year: "We believe that over the past few years we have laid the foundation for long-term growth by delivering innovative new products, creating opportunities for partners, improving customer satisfaction, putting many of our most significant legal challenges behind us, and improving our internal processes.

This year: "We believe that we continue to lay the foundation for long-term growth by delivering new products, creating opportunities for partners, improving customer satisfaction, and improving our internal processes." (Emphasis added.)

Thoughts on whether this language change is significant?
