Late on Monday and ahead of its media event tomorrow that is said to include updates to iBooks and possibly iBooks Author, Apple has opened the iBookstore in a slew of new countries, almost entirely in Central and South America (along with New Zealand). The media event, expected to introduce the "iPad mini" and perhaps other new products, has been rumored to include an update to the company's educational efforts and may indicate that the smaller iPad is being positioned for schools, education and e-reading.
