After the iPad 2 announcement earlier this week, many of you were probably thinking: How does it compare to the competition? We’ve put the iPad 2 against the Motorola Xoom, HP TouchPad, and BlackBerry PlayBook,  in a battle royale to see who is king of the tablet ring.

Interested in how the competition shakes out?

iPad 2 vs. PlayBook vs. TouchPad vs. Xoom

Size: The Motorola Xoom is the biggest kind on the block at 10.1”, and the PlayBook the smallest at 7” when it comes to physical screen size. Which of those is “better” depends on what you personally plan on doing with your tablet. The iPad and HP TouchPad both have the exact same size screen, 9.7”. Winner: Draw.

Thickness: The iPad 2 is the clear winner when it comes to thickness of the device. The iPad 2 is only .34” thick, while the HP TouchPad comes in at a little over half an inch (.54”). There’s not a dramatic difference between the iPad and TouchPad thickness wise, but .2” is something you’ll definitely notice when carrying the device around. Winner : iPad.

Rear Camera: The BlackBerry PlayBook and Xoom both have 5-megapixel rear-facing cameras, blowing the iPad’s camera, and the TouchPad’s no rear camera out of the water. Winner: PlayBook and Xoom.

Front Camera: The BlackBerry PlayBook takes the award for forward-facing camera. The PlayBook comes sporting a 3-megapixel forward-facing cam, a megapixel higher than the 2-megapixel cam on the Xoom, and loads better than the 1.3-megapixel cam on the TouchPad and VGA camera on the iPad. Winner: PlayBook.

Wireless Connectivity: All of the tablets have the ability to connect to 4G networks except the iPad, which remains 3G. Xoom customers who buy now are also forced to mail their tablet in for 6 days in order to score the 4G upgrade. Winner: Everyone but the iPad.

OS: We could fight the battle of what operating system is best all day long. In the end, the “best” operating system is the one that you’re most comfortable using, that does what you need it to. Winner: Readers choice.

Based on specs alone, the PlayBook and Xoom appear to be the clear winners in the tablet arena. The two tablets are able to take the lead because of the quality of their built-in cameras, something that may or may not matter to you as a tablet user. The particular OS a tablet is running is HUGE, but it’s also something you’ll have to decide for yourself.
