Samsung's Galaxy Note is coming to the U.S. on AT&T on February 19, and the "phablet"—that's part phone, part tablet—has already sold more than a million units worldwide.

This phone-tablet hybrid ("phablet"?) is meant to cater to those who want a bit of functionality from both camps. On one hand, you can make phone calls and access email, yet its supersized screen means you don’t need to squint to read e-books, watch video, play games or browse the web.

Is it a phone? Is it a tablet? ..no, it's a phablet.
