VisuAide Maestro

Two PDAs for the blind in two days. VisuAide's Maestro is actually an HP iPAQ h4150 Pocket PC that's been tricked out with text-to-speech and a special tactile keyboard that sits on top of its touchscreen. No braille matrix like the BrailleNote PK, but it obviously has all of the features that the h4150, like built-in Bluetooth and WiFi, and you can connect a braille keyboard to it.
