Lenovo IdeaTab Lynx vs Asus VivoTab Smart vs Lenovo ThinkPad Tablet 2 :Who is better?

Lenovo IdeaTab Lynx                                                                                                                                                                 The IdeaTab Lynx is well-balanced when plugged into its keyboard base, and offers good battery life, and a bigger-screen alternative to Lenovo's other Atom tablet.
But, The keyboard has too much flex, and the docking hinge sticks. For only a little more, better products are available.
The bottom line: The IdeaTab Lynx is a perfectly functional Windows 8 hybrid but lacks the lower price of some competitors, or better design and features of others.

Asus VivoTab Smart                                                                                                                                                              The Asus VivoTab Smart ME400 is as inexpensive as Atom Windows 8 tablets get, and the add-on keyboard/touch-pad combo is excellent.
But, The keyboard doesn't actually attach, which can be a hassle, and the folding magnetic cover takes practice to set up properly.
The bottom line: In a sea of hard-to-distinguish Atom-powered Windows 8 tablets, the Asus VivoTab Smart ME400 stands out a bit thanks to clever accessories.

Lenovo ThinkPad Tablet 2                                                                                                                                                      The Lenovo ThinkPad Tablet 2 is the best-looking Atom Windows 8 tablet yet, and the optional keyboard dock is excellent. All-day battery life makes it great for travel.
But, The Tablet 2 is expensive, especially considering the small 64GB SSD, lack of USB 3.0, and generally slow Atom performance.
The bottom line: This Windows 8 tablet from Lenovo scores with great industrial design and battery life, but adding practically required accessories makes the ThinkPad Tablet 2 very expensive for what you get.
