The April issue of About This Particular Macintosh is now available for your reading pleasure. Wes kicks things off with a look at what's been popular in the Mac blogosphere of late, and that's namely been about a product that isn't a Mac, but works with your Mac: the iPhone. The announcement of the software development kit (SDK for short) for the iPhone has generated quite a lot of discussion amongst developers and pundits. Mark talks about chips of all sorts, from his uniquely Brit point of view, as well as the latest DRM nonsense across the Pond. Charles has another Filemaking, and walks through relational databases. This month's desktop pictures are courtesy of several ATPM readers, and feature views from all around the globe. Thank you, all, for sharing! Back in meatspace, Todd turns the tables on the enemy with a reprogrammed Lisa. Cortland and Angela arrive safely from the Mudrix, but Cortland has paid a heavy price... My good friend Tom Bridge returns to the pages of ATPM with a look at The Book of Wireless. Lee rounds up the latest iPhone accessories from Newer Technology, while Ed puts PhotoAcute Studio through its paces. Paul is pleased with Take Control of Permissions in Leopard, and Ellyn closes out the Tome Edition™ of ATPM by digging through Wikipedia: The Missing Manual. As always, you can read ATPM online, as well as in three other formats of your choosing. Thanks for reading!
