Is it a phone, a tablet, or a "phablet"? The Samsung Galaxy Note, with its stylus and gargantuan 5.3-inch display, walks the tightrope between smartphone and slate. Whatever you call it, the Galaxy Note is a hit with consumers worldwide. So what's next? Samsung has an announcement scheduled for Aug. 29 at IFA 2012 in Berlin, and rumor has it that the second-generation Galaxy Note will debut at the show. The new phablet's screen is expected to be larger than ever at 5.5 inches, but the device itself might be slimmer than the original monster phone.
