PetManimal writes "A comparison of first-week retail sales of Vista compared to first-week sales of XP back in 2001 found that Vista sales were 60% lower. Steve Ballmer has admitted that earlier sales forecasts were 'overly aggressive,' but at least there is some good news for Microsoft: early Office 2007 sales were very strong compared to the early sales of Office 2003, despite almost no advertising or marketing until the retail launch at the end of January."

An anonymous reader slipped us a link to the Seattle PI article discussing Bryan Lee's departure from Microsoft. The former business development VP for the Zune has parted ways with the company for personal reasons now that 'Zune was launched and on track'. This means that J. Allard will be stepping up into fill the void. Allard was instrumental in bringing the first Xbox console to market, and was the VP in charge of technical matters for the Zune. An analyst with Gartner is quoted as saying this move means not all is well in the land of Zune, but a rumour on the CrunchGear site indicates that Microsoft is planning on stepping things up later this year with a Zune cellphone. A smartphone designed to compete with Apple in that market it would seem, despite whatever problems may be going on, the company is still rather fond of the strange little brown device.

amigoro writes "Most believe that the ice ages are the result of subtle changes in Earth's orbit, known as the Milankovitch cycles. According to one scientist, that is not the case. Robert Ehrlich of George Mason University in Fairfax, Virginia, has developed a model which hypothesizes a dimmer switch inside the sun that causes its brightness to rise and fall on timescales of around 100,000 or 41,000 years, exactly the same period as between ice ages on Earth. The main problem with Milankovitch cycles is that they can't explain how the ice ages go from 100,000 year cycle to 41,000 year cycle. The cycles predicted by Ehlrich's model line up with the observations."
