HP isn't really trying to keep its 12.1-inch EliteBook 2760p convertible tablet a secret these days, but honestly it might not matter even if the company tried -- the ever-reliable FCC made plenty of pictures and documentation available in a filing by Sierra Wireless. That's the company that supplies the Qualcomm Gobi3000 dual-mode GSM / CDMA cellular radio in this tablet, you see, which should be an attractive option for business travelers -- though we don't see any mention of it in the first three Elitebook 2760p models confirmed on HP's website. What's that, you say? Confirmation? Yes, indeed, as HP is already listing three versions starting at $1,499, with the base model nabbing you a 2.3Ghz Core i5-2410M, 4GB of DDR3 RAM, dual-band 802.11 a/b/g/n WiFi and a 320GB hard drive.
