    I have a 6350 and can confirm that it will scan at 1200dpi optical
    resolution. Any resolution thereafter will be handled in software. If
    I do a 1200dpi color scan uncropped, the resulting image saved in
    xscanimage is *huge*, roughly 800MB or so.

    I just fired up xscanimage and noticed that the "bit depth" option in
    "Advanced Properties" only contains "8, 10, and 12" for the selection?

     From the box:

    1200 dpi optical resolution
    1200x2400 dpi hardware resolution
    36-bit color

    I'm not an expert on some of this marketing spin, so make of this what
    you will. The resolution seems a no-brainer, but the bit depth may need
    further investivation. FWIW, for the price of this scanner, you
    *should* get true 36-bit color, but I don't know for sure. Sorry.
