You may not want to hear this, but TechRepublic's editor-in-chief, Jason Hiner, decided that of the 10 best smartphones of 2010, the Samsung Vibrant ranked #4, up there with the Droids.
I have had NO ISSUES WHATSOVER with my Samsung Vibrant. It executes operations quickly, launches calls and Visual Voicemail easily, and is slim in the hand. PLUS, the SuperAMOLED screen is truly the most remarkable (sharpest, most colorful, best contrast) cell phone screen out there, short of Apple's iPhone Retina Display.
Also, the LV Valley and Southern Cali 3G networks are stable and fast.
