From Slice Intelligence:

The number of iPhone SEs bought the first weekend of availability was 94 percent smaller than the iPhone 6S launch, which was 46 percent the number of iPhone 6 devices sold when it was released.

But:

Early data from Slice Intelligence indicates that the SE may help Apple grow its maturing iPhone consumer base. Only 35 percent of iPhone SE buyers purchased an iPhone online in the past two years, and 16 percent of them were previously Android users. By comparison, 49 percent of iPhone 6S buyers upgraded from a previous iPhone, and 10 percent replaced an Android device they bought online within the past two years.

Interesting numbers. Looks like the iPhone SE is doing its job, filling in a hole in the product line and bringing outside customers into the ecosystem.
