This week Microsoft (disclosure: Microsoft is a client of the author) announced the Microsoft Surface Go.
This is an original iPad sized Surface product with a base price of just under $400 that uses a Pentium processor and has 9 hours of battery life.
While the iPad is clearly the competitive target, particularly in education, you can also see it as a hedge against the Chromebook which has been making inroads in education and in a lot of trials, but few (if any yet) successful deployments in the enterprise market.
