The Orbo Jr and the Chromo tablet are in most respects identical. The Orbo Jr will do everything that the Chromo will do.
Screen resolution (1024×600), size (7″) and hard drive (4GB) are all identical for the two tablets. Both run Jelly Bean Android OS, both have built in WiFi and camera, 512 MB of RAM, the same battery life and external memory slots allowing the memory to be increased using an SD card. For many intents and purposes, the two tablets are identical.
The primary difference is in the colourful protective silicone gel case that the Orbo Jr is encased in, which provides added protection for younger hands that might be more likely to drop it, and break the screen. In other respects, it’s a proper tablet, just like the Chromo. With the Orbo Jr, your child is getting a proper tablet but with added protection from damage.
