Argos has launched its first own-brand android tablet computer in time for Christmas. The 7in MyTablet will retail for £100 and run on Google's Android Jelly Bean OS. This launch follows Tesco Hudl which launched last week at £119. Argos are hoping to hit the 'tweenie' market of 8 to 13 years old and pricing it so everyone in the family can have one. Will this be a success?
