Samsung Electronics Co. Ltd.’s new supersized tablet—the 12.2-inch Galaxy Note Pro—is perhaps the most exciting mobile device on the market today. But before you whip out the credit card, hang on: You probably don’t want to buy it, at least not yet.

The tablet comes with a significant price tag ($750 for the entry-level model), and like a lot of recent products (here’s looking at you, Surface 2), it definitely falls into the “not quite there yet” category. There’s the fact, too, that it runs on Android, a great mobile operating system but one that still lags behind Apple Inc.’s iOS when it comes to the breadth, and often the quality, of apps, particularly legal and business titles. More than any other tablet, this device demonstrates the unique and largely untapped potential of tablets, and even starts to deliver on it. So while you may not want to buy Samsung’s beast, you should keep your eye on it—and better yet, the tablets that follow, and improve upon, its lead.
