As the name implies, the HP iPaq 510 Voice Messenger is a smart phone that focuses on voice features, whereas the company's previous model, the HP iPaq hw6945 Mobile Messenger had an emphasis e-mail and messaging.
The iPaq 510 Voice Messenger has 128MB flash ROM and 64MB SDRAM with about 65MB available for storage and 44MB for program memory. For large files, like music and videos, take advantage of the microSD card slot.
One of the complaints about Windows Mobile devices is that it takes too many steps to accomplish one task. HP has somewhat remedied that situation by adding a shortcuts page for frequently used applications and functions.
The HP iPaq 510 has outstanding voice-command capabilities. You can call contacts, reply to e-mails, play music, and more, all with just the sound of your voice. We tried it out, and it worked great--no training required.
