I don’t recommend that average iPad Air owners upgrade to the Air 2. But what about the vast majority of iPad owners who own older models? That’s a different story. If you have an iPad 2, 3 or 4, the new Air 2 will make a big difference. Its thinness and lightness will be a dramatic change, and it will be faster and more fluid. However, here’s the catch: Upgrading to last year’s iPad Air would have pretty much the same effect, and that model is now, suddenly, $100 cheaper, starting at $399.

It is possible to make buildings by stringing together patterns, in a rather loose way. A building made like this, is an assembly of patterns. It is not dense. It is not profound. But it is also possible to put patterns together in such a way that many patterns overlap in the same physical space: the building is very dense; it has many meanings captured in a small space; and through this density, it becomes profound.
