Samsung has announced a replacement for its original seven-inch Galaxy Tab Android tablet, with an upgrade to a dual-core 1.2GHz processor. The Samsung Galaxy Tab 7.0 Plus is faster, thinner, lighter, and adds HSPA+ service -- plus, it should be inexpensive, considering the competition from Amazon's $200 Kindle Fire and HTC's Flyer (about to be slashed to $300). The Galaxy Tab 7.0 Plus will launch in October in Indonesia and Austria, followed by the U.S. and other countries at a later date.
