- The Samsung Code (SCH-i220) is MetroPCS's first Windows Mobile 6.1 smartphone, which seems like a step backward seeing as Windows Mobile 6.5 devices are available.

- Magellan RoadMate 1470
- Design The RoadMate 1470 doesn't deviate from the tried and true portable navigation device form factor. Measuring 3.3 inches by 5.2 inches by 7 inches, the RoadMate's thinness easily makes this unit one of the most pocketable devices in its class. Like nearly all PNDs, the majority of the RoadMate's...

- Samsung HZ15W
- The Samsung HZ15W is a camera that looks good on paper but doesn't live up to the specs. The main attraction is the 24mm-equivalent wide-angle lens with 10x zoom, which is certainly a plus in a camera this size, giving you a lot of shooting flexibility for less than $280....
