Treo 600 vs Audiovox SMT5600

Here's a shot of my PalmOne Treo 600 and BigMac's Audiovox SMT5600. As you can see . the Treo is quite a bit larger, but that gives it a larger screen. The similarities are striking, both of us have installed 1GB cards and use the phone as our MP3 player. Both PDA's are pointed to Mobile Optimized.
