Tablet company Archos has just announced what may be the cheapest mainstream tablet we've seen yet: the Archos Child Pad, a $129 device with a 7-inch screen and Android 4.0. The Child Pad looks very similar to the $199 70b Honeycomb tablet, but the specs are a bit different — you'll get a 1GHz processor and 1GB of RAM. It's not clear how much storage or what kind of screen it includes, but we wouldn't be surprised if it had the same 1024 x 600 capacitive display as the 70b.

Archos says it's also made some tweaks to Ice Cream Sandwich for the Child Pad, adding a custom skin, some pre-loaded games like Angry Birds, and stronger parental controls. The tablet will start shipping at the end of March. Archos doesn't have the best track record for build quality, so we're not convinced that the hardware will be good enough to justify buying it even at such a low price. Still, hopefully it's a sign of more cheap Android 4.0 tablets in the coming months.
