Microsoft Windows Vista Beta 2 continues to grow more and more popular and as a result APC Magazine says that Microsoft intends to release Vista Betas each month. Jeff Putt told sources that the release of future betas depends on the complexity of the bugs that are found but their goal is to fix the bugs as quickly as possible.
He also talked about the shorter battery life that notebook users were experiencing when running Vista:
This is still beta 2 code. [GPU heat and power consumption] also relies on third parties and their graphics drivers – and they are coming along.
I think that he made a good point because people using the Aero interface are extensively using the Graphics Processor Unit (GPU) which will shorten the battery life. Once the manufacturers of the video cards get stable drivers released then we might start to see the normal battery life that is expected.
