Dell has another Inspiron Duo-style convertible tablet in development right now, as shown by the recent FCC documents for a model dubbed Dell Panerai. This can be considered heavier and larger Duo, possibly with a 15 inch display, if Engadget’s speculations are correct. The size of the sticker on the back is an indication for that.

As far as specs are concerned, all we know is that the Dell Panerai comes with WiFi 802.11 b/g/n possibly an Intel CPU and most likely the usual ports available on such devices: USB, HDMI, audio and a card slot.
