As my subject line suggested, Samsung folks have been studying all the complaints and grips about the HTC/Tmobile G1 and launched their iteration with style and performance. Engadget has the details on specs so I won't go there. What I will mention is why it will be superior over the existing G1.
1. Physical Appearance: Much more refined looking and get rid of the annoying looking chin. This image rendering looks more professional duty by design and looks to have all the buttons much more accessible and laid out.
2. Feature rich + improvement: WOW! AMOLED display at 320x480. 5 Megapixel camera w/ LED flash. Tri band 3G (900/1700/1900) 1,500mAh battery (much needed improvement over G1's meager 1150mAh) and finally, in the words of Barney Stinson... "wait for it...wait..." 3.5mm audio jack!!!
This thing is pretty exciting. It just might convince me to make the switch again! Looks like Samsung is back and on top of the mobile biz.
