While it is important that there are opportunities for use of different learning styles, (such as the blogger wanting to be able to take notes during a talk) there will also be others that learn differently.
The blogger may find it best to take notes on everything that the professor is saying - there are others for whom it will be most productive to sit and listen intently and not take any notes at all.
The problem seems to be then, not the PowerPoint itself, but the pacing that the professors use. If they are to do problems on PowerPoint, they should have the steps appear gradually as they are working through the problem, and use the appropriate pacing, to ensure that students have the opportunity to follow the problem.
As for not having handouts of the PowerPoint slide, or their availability being in some way a disadvantage - I would say it's time to grow up. Adults are responsible for their own learning. If someone knows that they learn best by taking notes, then take notes anyway. The availability of the notes after the class will be something very positive for many others, and to request that the notes not be available for their sake is to fail to recognize the learning needs of others.
