The company gave no timeframe for the forecast sales of the Note, which is already available in other countries. The Note, with a 5.3-inch (13.5 centimetre) screen, is positioned between the firm's flagship Android-equipped Galaxy smartphone and its Galaxy Tab. The Note, with a larger screen than the smartphone but smaller the than tablet, suggests the company is seeking a head start in the market for a model combining both functions. Samsung said the device combines the portability of a smartphone with the larger screen of a tablet. "Galaxy Note is a revolutionary product opening a new category in the market," said JK Shin, head of the mobile communications business, in a statement. The firm also launched the Galaxy Nexus, the first smartphone to run on Google's newest Android operating system which has been dubbed the "Ice Cream Sandwich".
