HTC has certainly customized this tablet as you can tell from the screenshot of the QWERTY which shows that a numeric pad will be used for quick entry of numbers. Besides the bloatware that AT&T so generously added to the device, HTC Hub will be onboard, offering more content for the tablet. One of the screenshots shows a syncing tool available for the HTC Puccini's users. As far as connectivity goes, the device is heading to AT&T for the time being and the H+ on the pictures reveals that it will be the carrier's HSPA+ network putting the 4 in 4G for now. Eventually, an LTE model could be available for AT&T customers.
