Though this is not really Visio related, I would like to talk about the Zune HD I acquired in February. So far I like the device, but as an MVP I cannot keep my mouth shut when it comes to talking about ways to improve.
The Zune designers for the desktop software should take a look at the Data Graphics in Visio. The podcast collections could be improved by adding a Data Graphic like feature to the podcast labels to indicate if it is to synced, how many times and how many podcasts are kept. The current method required you to select a collection and then click the settings button.
One of the features of PowerPoint 2010 is that you can save a presentation as a WMV file. When the file is added to the video collection on the Zune HD, the forward and backward buttons will take you to the transition point on the next or previous slides in the presentation. This makes for a very nice portable PowerPoint presentation device. Of course, you have to obey the standard presentation rules and avoid busy slides. If the slide is not readable on the Zune HD it is definitely too busy for a regular presentation.
