The Raspberry Pi Foundation has unveiled a smaller, cheaper, lower-powered Pi 3, the Raspberry Pi 3 Model A+. The new model will sell for $25 USD and has lower power requirements with less RAM than the 3B+ (512 MB DDR2), only a single USB port, and no Ethernet port. However, it has the same BCM2837B0 quad core processor running at 1.4 GHz, a dual band WIFI networking, Bluetooth 4.2 Low Energy connectivity, the normal 40-pin GPIO header, and audio and video output.

That's 40% more! If you're just buying one that may not a big deal - if you're buying in bulk (say, for a school/college, or building a commercial product around them) that's a very significant difference.
For individuals, part of the appeal of the Pi is that you can tinker with it and, if you screw up and let the magic smoke out, no big deal. Or if you've built something and want to start a new project, no need to rip the old one apart to extract the expensive computer. Or, you may want to run one on batteries in a drone or something - less components generally means low power. One of the appeals of the Pi is that they have stuck to the low cost principle and haven't let the price creep up.
