"Can’t imagine the extra size of Touch HD when compare to HTC Touch Diamond? CNet Asia has got a nice side by side comparison photo on the 3 HTC Touch series. Obviously because of the WVGA resolution, the Touch HD is wider and bigger. Even that I am sure many of you can’t resist the beauty of higher resolution.On the thickness comparison, the HTC Touch HD (115 x 62.8 x 12 mm ) about the same as the same as HTC Touch Diamond (102 x 51 x 11.5 mm). The Touch Pro is much thicker due to the additional QWERTY keyboard." More photos here:
