Ian Lamont writes "Bill Gates, in an address to the TechEd Developers conference, talked about Microsoft's plans for hosted services, and revealed that the company is planning data centers on 'a scale that we haven't thought of before' that will apparently enable the company to offer all of its server-based products over the Internet. The talk did not include details in terms of capacity or scale. This was Gates's final publicly scheduled speech as a full-time Microsoft employee, and he acknowledged that Microsoft's success is 'due to our relationship with developers.' On July 1, he will start spending most of his time at The Bill and Melinda Gates Foundation." After that date he will be devoting his "20% time" to Microsoft.
