daedworthy, trying to use an iPaq as a phone. If your device has bluetooth functionality, why not try using a bluetooth headset with it for voice calls? Another cool idea is to install Skype on it and use a home wireless LAN or free WiFi hotspot to make voice calls via Skype on the iPaq (again, preferably with the bluetooth headset).
The iPaq that I used to have was quite awesome for its time, and even had a 1GB MicroDrive which was molded into a sleeve for the iPaq, which seemed like a Terrabyte of storage space compared to the measly 64MB of installed RAM in the device. No, I couldn't imagine using something that bulky as a telephone. These days I have an HTC Apache, which has all the features of a Windows Mobile 5 based PDA, far superior to the old iPaq, and much easier to use as a telephone, even without the aid of a bluetooth headset. The iPaq wasn't actually mine, unfortunately, but was one of the perks of my job. The Apache that I own now is mine, and I use it all the time for all sorts of things. When they saw my Apache and the way that it was configured, the local telephone retailer said that it was the first time that they had ever seen someone making full use of all the features of a smartphone before! Yeah, I'm a power user of embedded systems, and I'm always looking for new ways to use my smartphone, either with software or hardware add-ons. I have a bluetooth wireless infra-red keyboard and a bluetooth headset. I'm hoping to get a bluetooth stereo headphone system soon for it, and I've played with a bluetooth mouse on it before. I'd also like to get a GPS connection for it one day too.
The iPaq? It went back to my boss and I've never looked back. There's always something new around the corner!
