The Tab 2 has a dual-core processor, not quad-core like the ASUS Transformer Prime, and will ship with Android 4.0 Ice Cream Sandwich. Unlike the 10.1-inch Galaxy Tab on the market now, the Tab 2 will have a micro SD slot to expand the on board storage (16GB or 32GB). Samsung will offer Wi-Fi only and 3G versions; no mention of 4G.
GNote owners have a wide range to choose from, including a cover from Samsung that adds minimal extra thickness and weight to the already large phone. Plus, the best cases take a cue from the Note's versatility and do more than just protect.
