How does a company known for voice recording jump on the e-mail bandwagon? Combine the two and start pushing inchvoice e-mail.inch That's Dictaphone's strategy with its Walkabout Quest and the company has thrown in a synchronizing organizer for good measure. The Walkabout Quest PDA has no modem, though, so it has to be linked to a PC for communications capability. You create a voice memo by speaking into the Quest's microphone, tapping a recipient name from the address book and hitting Send on the touchscreen. Quest converts the memo into a .WAV file and it scoots through cyberspace as an e-mail attachment. You can download e-mail messages to the device, leave the office and then respond by voice as you read or listen to each message. Each removable 2MB memory card stores 40 minutes of audio.
