After riding the trend of blurring the line between phone and tablet with its iPhone 6 Plus and 6s Plus, Apple is going the other way with the iPhone SE — a device with a screen the same size as the iPhone 5S, but with the same chip as the 6S.

Even though Apple hasn’t made a 4″ iPhone since releasing the 5S in 2013, the company said today that it managed to sell more than 30 million of these smaller-screen devices in 2015 — many of them to first-time customers and in emerging markets like China.

Dubbed “the most powerful 4-inch phone ever,” the SE features the same A9 chip and motion co-processor as the 6S, meaning it has the same processing performance and graphics as the bigger device. It also features a 12MP iSight camera.

The big selling point: The $399 price; that’s the least that Apple has ever charged for a newly released iPhone. If you have a wireless provider that still offers two-year contracts, the SE would be free of charge with a re-upped contract. For people paying on two-year installment plans, expect to pay $17/month.

Pre-orders for the SE start March 24, with the actual device being available March 31

On those same dates, Apple will be selling a new, smaller iPad Pro with a 9.7″ screen — about three inches smaller than the first generation Pro. With that trim in size comes a cut in price. The larger Pro started at $799, but the new, smaller version starts at $599.

In addition to the change in screen size and price, Apple says the new Pro features several upgrades to the original — including a 12MP camera that lets you shoot and edit 4K video on the device; a “True Tone” display that senses ambient light and adjusts accordingly, and better speakers.

Both versions of the Pro will also be available with 256GB of storage for an upcharge.

Apple also reduced the price on Apple Watch to $299.
