A fresh rumour has surfaced suggesting that Apple may be sampling 8-inch tablet displays from AU Optronics and LG Display, according to WSJ . Apple is known to experiment with different displays for its devices, which do not always make it to market. However, while most people opt for 10-inch tablets where the iPad dominates, smaller tablets such as the Amazon Kindle Fire have made significant inroads into the expanding tablet market, costing Apple total market share.
