Lenovo unveiled three new tablet computers, marking the first time the company is prepared to sell a mobile device worldwide.

The IdeaPad K1, running Google's Android mobile operating system, is already available for preorders and will ship in August. The 10.1-inch tablet will directly compete with the iPad. The IdeaPad has 32 GB of storage and is priced at $499.

Lenovo also said it will begin taking orders on August 2 for the ThinkPad Tablet, which will also use Android and feature a 10.1-inch display. The ThinkPad tablet will feature both rear- and front-facing cameras. This will be the business-oriented tablet, offered in 16 GB ($479) and 32 GB ($589) models.

The third tablet will run Windows 7, a rarity thus far in the tablet market. Labeled the ThinkPad Tablet P1, the 10.1-inch Windows tablet will be available in the fourth fiscal quarter for an undisclosed price. In addition to a 1.5 GHz Intel Atom processor, the Lenovo IdeaPad Tablet P1 has a front-facing 2-megapixel camera.

Each of the three tablets will include both Wi-Fi and Bluetooth connectivity.

Lenovo's tablets will be the first tablet computers to be certified for Netflix. The tablets include the necessary Digital Rights Management (DRM) technology, as well as HDMI ports built. Users of the IdeaPad and ThinkPad tablets will be able to watch Netflix and other content directly on a television.

Lenovo's new tablets are the latest entrants in the tablet market, although iPad sales are unmatched. The IdeaPad and ThinkPad tablets will also compete with Samsung's Galaxy Tab, particularly the latest Galaxy tablet with a 10.1-inch display.
