TidBITS#423/01-Apr-98 - Apple rocks on this week, with announcements of network computers, new low-priced desktop Macs, and changes to QuickTime's pricing structure. Also this week, TidBITS issues a security challenge, Peter N Lewis of Stairways Software ships a hot new utility, and BoxTop Software finally makes it possible to export HTML from Adobe Photoshop. We round out the issue with a look at VST's EB-451 for PowerBooks with expansion bays.
