Griffin Technology today announced the iMate, a $29 USB-to-ADB adapter that enables iMac users to use standard ADB devices such as keyboards, mice, trackballs, and joysticks. Plans for a future version include support for less standard ADB devices such as copy-protection dongles. iMate users will be able to mix and match USB and ADB devices, and ADB devices attached to an iMate can be daisy chained. Reportedly, the iMate also enables USB-equipped PCs running Windows 98 to use ADB devices. The iMate is schedule to ship in mid-August, corresponding with the iMac release date.
