Apple today announced the eighth-generation iPad mini, introducing a larger OLED display, a thinner and lighter design, the A20 Pro chip, and water and dust resistance, but how much does it differ from the previous model? The new iPad mini starts at $699 for the 128GB Wi-Fi model and $849 with cellular connectivity. With the prior generation now discontinued, buyers also face a choice between paying for the new features and finding a cheaper A17 Pro model.
