A kid-friendly tablet often isn't enough by itself to keep little tykes happy -- you have to get the content they want, too. Polaroid is counting on this formula to lure parents to its newly available Kids Tablet 2. The 7-inch slate comes preloaded with the full versions of 70-plus apps and e-books from Cartoon Network, Disney and Marvel, giving children plenty to do right from the start. It's also a big step up in performance versus the (frankly pokey) original. Along with a software upgrade to Android 4.2, the new Kids Tablet carries a dual-core 1.6GHz ARM Cortex-A9 chip, 1GB of RAM, a 1,024 x 600 screen and a front camera to complement the existing rear sensor. Polaroid's tablet isn't the cheapest in its class when it's selling for $149 through Toys R Us, but it may save adults the trouble of hunting for software.
