Although Tablet PCs have been around for ages, the Apple iPad takes credit for revolutionizing the tablet market. Nearly six months after its debut earlier this year, a noteworthy competitor is still missing. Fortunately, that’s all about to change: Samsung’s upcoming Galaxy Tab runs on Android, has two cameras, support for video chat, and offers other features the iPad lacks. In addition, most reports indicate that a subsidized 3G iteration will launch on AT&T, Sprint, and Verizon this year giving it a boost over the AT&T-only iPad 3G. However, with Apple’s upcoming iOS 4.1 update, larger App Store, and established market share, Samsung faces stiff competition.
