Hold onto your hats, Motorola fans! As the launch of the nation's first mobile WiMAX network (hopefully) draws near, the company's announcing its first ever USB WiMAX device, the USBw 100. This thumb-drive-sized slice of heaven will be available in three flavors, providing high-speed mobile broadband on your 2.3GHz, 2.5GHz or 3.5 GHz network. No pics, pricing or definite release date yet, just the vague promise that we'll be seeing her in the fourth quarter of this year. We're all giddy in anticipation.
