Samsung has at long last made the release of its Galaxy Note 10.1 official, promising to have the stylus-equipped Android tablet on store shelves "globally" by the end of this month. Equipped with a 1.4GHz quad-core processor and 2GB of RAM, the Note 10.1 offers a fine spec upgrade over Samsung's previous 10-inch tablet efforts, while also expanding the Note lineup in form factor from the original Galaxy Note's 5.3-inch dimensions. In terms of connectivity, you'll get a choice of Wi-Fi-only, Wi-Fi plus 21Mbps HSPA+ 3G, or Wi-Fi plus LTE, with the 4G-capable model coming a little later in the year.
