iPad 2 (AAPL) Ready to Take on RIM (RIMM), Motorola Mobility (MMI), Verizon (VZ), HP (HPQ), Dell (DELL)

RIM (NASDAQ:RIMM), Motorola Mobility (NYSE:MMI), Verizon (NYSE:VZ), HP (NYSE:HPQ) are all taking aim at Apple's (NASDAQ:GOOG) iPad, as the anticipated unveiling of the iPad 2 is set for Wednesday.

Research In Motion Ltd., maker of Blackberry, is expected to ship its PlayBook tablet in either March or April at a price-point close to the iPad, which starts at $499. The PlayBook's major selling point: it will have tighter security and integration with corporations' back-software.

Motorola Mobility Holdings Inc., meanwhile, just launched Xoom, a tablet that will support 4G, the next generation high-speed wireless network, through Verizon Wireless for $599 with a two-year contract.

Hewlett-Packard Co., Dell Inc. (NASDAQ:DELL), Motorola Mobility, and Toshiba Corp. are all also preparing tablets to launch in 2011.
