It so happens that the most popular device manufacturers have started making products that offer top specs while reaching for the affordable side of the market. It is the case with Google, Amazon, Nook and Apple, who launched very good products in a close to low price category.
Sure, Apple products will never be as cheap as one would hope for. They charge over $300 for the cheapest version of one of their latest tablets that wants to be affordable while keeping the hardware at a mid level and a high end design and choice of materials. The iPad Mini is certainly not one of the cheapest tablets. For what the Mini offers you could do a lot better choosing an Android device. If you are willing to spend a bit more you could even get the Nexus 10 with a screen resolution higher then even that of the iPad 4.
Still through aggressive marketing campaigns and lots of fans around the world, Apple managed to sell their entire iPad Mini stocks. There are short supplies for all variants, especially the LTE variants with the 32GB LTE iPad Minis to be delivered somwhere at the end of November. According to SlashGear andMacworld.uk, preordered LTE iPad Minis will ship somwhere from late November to December.
