Conclusion: The HP iPAQ 310 Travel Companion is the first GPS device to use a speedy dual-core processor. When it's coupled with a high-resolution widescreen display, the results are pretty impressive.
Pros: Powerful dual-core Titan processor. High-resolution widescreen display. Forty-channel GPS receiver. Excellent 3D rendering. Buildings rendered in 3D in 40 U.S. cities. Multisegment routing.
Cons: Power connects to device directly, not via mounting bracket. Text on the bottom of the screen is a bit small.
