The TechZone has an editorial asking when Google will start selling hardware.
Google has also produced a variety of applications designed specifically for the mobile environment. Gmail comes in a mobile version that is better suited for the smaller screens of Pocket PC devices. Google Maps have worked very well with KDDI cell phones in Japan, though they have yet to make quite as big a splash in North America. With all of this "software" development, Google is starting to look like the new Microsoft, so... you've got to wonder, when will Google finally take the next logical step and actually produce some branded hardware?
