Apple's iPad is one of the fastest-selling devices in history. But just because most people bought iPad doesn't mean you should. There are now many iPad contenders in the market. Here are just five of them:

1. Samsung Galaxy Tab 10.1V
The stand-out feature of the Samsung Galaxy Tab 10.1V, the best selling tablet after iPad, is its 8MP rear-facing camera. Sitting next to an LED flash on the back of the device, this powerful camera blows the iPad 2's 0.7MP effort into oblivion. The tablet's screen is a 10.1-inch TFT with a resolution of 1280x800. It is powered by Nvidia's dual core Tegra 2 CPU and has 1GB RAM.

2. Asus Eee Pad Transformer
ASUS answers typing struggles with tablets in the form of the Eee Pad Transformer TF101. The tablet comes with keyboard dock that not only makes typing but easier also doubles the battery life and boosts connectivity. It has a 10.1in (1,024x800 resolution) capacitive screen, an NVIDIA Tegra 2 (1GHz) processor, 1GB of RAM and operates on Android 3.0.

3. Acer Iconia Tab A500
Compared with the iPad, the Acer Iconia TAB A500 has a richer selection of ports and slots. It has a micro-USB 2.0 port, a mini-HDMI port for streaming video to TV and a MicroSD slot. The Acer tablet also has 5 MP auto focus camera at rear and 2 MP camera at front. It is powered by Nvidia Tegra-2 1 Ghz dual core processor and comes with 1Gb DDR 2 RAM.

4. LG Optimus Pad
LG Optimus Pad is the first tablet capable of displaying 3D video and still images. The tablet boasts an unorthodox 8.9-inch display with a 1280 x 768 resolution. It has dual-5MP cameras which work together to shoot 3D images and record 3D footage. A dual-core Tegra 2 chip makes up the silicon guts, along with 32GB of storage and Android 3.0 Honeycomb.

5. Motorola Xoom
The interesting thing about Xoom is that it has a PC like interface so you won’t feel uncomfortable after switching from your PC. It runs Google's Android 3.1 Honeycomb and uses Nvidia Tegra 2 SoC. The 16:9 aspect ratio of the screen makes it well-suited for watching widescreen videos.
