Hey look, the Flyer just got itself a bigger brother. A 10-inch tablet codenamed the HTC Puccini has been revealed by our old buddy 911sniper (who has a habit of finding and leaking HTC ROMs), living up to a longstanding rumor that places two 10-inch Android slates on HTC's roadmap for this summer. It's said to pack LTE for Cingular (AT&T) in the US and to be built atop Android 3.0.1. A dual-core 1.5GHz Qualcomm MSM8660 offers plenty of processing power and screen resolution should match the 10-inch pack with 1280 x 800 pixels. Gazing at the above screenshot reveals a UI very similar to the Flyer's Sense 3.0 look, including the Notes app being in a prime position, which could very well mean Magic Pen compatibility will also be part of the Puccini's arsenal. You'll know more about this as soon as we do.
