A Slab Of Glass is in the midst of a change of focus, by the way. It was originally supposed to be iPad-focused… then one of the two hosts pretty much stopped using his iPad. I had a hard time making it through the last podcast episode, which consisted of a lot of talk about why it took so long to put out the latest episode, discussed procrastination and health issues and meandered a lot more than I found palatable. (I’m giving it one last chance before I delete it.)
I’d suggest instead checking out Let’s Talk iOS from idownloadblog.com, and AppStories , and maybe Bring Your Own Device. For Mac/iOS/games I like the Ruminate podcast.
For a more general Apple podcast I recommend the 9-to-5Mac Happy Hour, which isn’t as popular as perhaps it should be.
Canvas was great, and I really appreciated the increasing skepticism Fraser Spiers had towards the iOS ecosystem with regard to schools and their limited budgets. (He almost convinced me to buy a Chromebook!)
