I wish they would release a model that supports 3 cameras and has built in Galileo GPS. Oh and a SATA connector for storage.
A new Raspberry Pi takes a bow with all of the speed but less of the RAM
Like the Raspberry Pi 3 Model B+ but feel that the RAM is just a bit too big, the price too high or the ports too numerous? Fear not, for the spiritual successor to the original Model A+ is here. Launched today, the Pi 3 Model A+ rocks the same processor as its bigger brother, the 3B+, in the form of a 64bit Cortex-A53 …

Re: 3 cameras
You might be interested in the IV Port from Ivmech - pricey, but lets you multiplex four cameras on the Pi's CSI port. You can even stack four of them together, for a total of 16 camera inputs...

Re: I would rather
By put to sleep, what do you want to continue running when it is sleeping? How quickly does it have to resume from sleep, and what triggers it to do that? For most available triggers, WiFi signal for example, enough of the system remains up in order to receive and decode that that there is little benefit to putting it to sleep.

Please be careful with designations....
The article makes a reference to a "Pi B". Please guys, there *is* a Model B (and a B+). The comparison today is between the Pi3B+ and the Pi3A+. The first generation boards (using the BCM2835) are the only ones that don't usually get a "generation number" included in the common name. (Officially, if you look at the box, the Pi3B+ is a "Raspberry Pi 3 Model B+". That "3" is important to know what you're discussing.)
The real confusion comes when discussing the Pi2B. You have to specify whether it's a Pi2Bv1.1 or a Pi2Bv1.2 as the SoCs are different.

Re: Just a wee little point
It is the price of the pi zero with wifi built in, which I see as this model's main competition. That lacks plenty of the features of this model, but it does offer most of the ones wanted for running headless*. The processor is slower, which would be painful if using it directly or if it has a lot to drive, but it is very low on power usage, also has built in networking, the same memory, and can use the same hardware on GPIO. If you're using something running a GUI or using a bunch of processing, you're probably going to want the 3B+ anyway for the ability to use USB accessories. Similarly if you're going to attach this as networking equipment because ethernet will probably be desirable. For me, all use cases where I don't want either of these will be decided in the zero's favor because it is smaller and requires less power to run. Those can be critical.
*headless use of pi zero: set up the environment on something else so you can have a more convenient experience, then enable SSH and move the card over.

Not sure I get the logic for reducing RAM capacity, OK, so it sucks a little more power but a memory constrained system has to be the worst design option out there and I have a deep loathing for machines with low RAM as they are ALWAYS slow as they are constantly swapping. On a Pi, that translates to it eating your memory card quicker. Surely the power cost on the SD card and performance impact outweighs the power reduction from the reduced memory size ?
+1 for adding a SATA / mSATA connector (on some high speed bus, not crippled behind USB) as it means higher performance and I won't need to have to rebuild system X in 18 months when it eats the next microSD card and starts acting all weird and takes me a while to work out what the problem is again.
I'd happily pay for a "Model C" - where C is all about capabilities, not price. I don't care if the board is bigger and has free space for options I've not populated (mSATA) or uses some form of stacking arrangement like PC104 used to.
They are great little boards and I've got them doing all sorts of handy jobs, but they could do a lot more for the higher end hobby and business markets, rather than just focusing on the maker/educational end of the spectrum.

USB-C port
I love the USB-C standard, and have it on my laptop.
Thoughts on why USB-C is not on Rasp PI? I guess that having a separate HDMI output is no big consumer os space, and it allows hobbyists and schoolchildren to hook up a cheal HDMI Cable to a standard television. With a USB-C port you would need a separate hub to fan out to HDMI, stanrard USB for keyboard and mouse, and for ethernet. Which would cost more than the Rasp PI
Also I guess USB-C chipsets aren't integrated with the SoCs used on Rasp Pi.
Thoughts?

Re: USB-C port
HDMI also allows a simple, cheap cable to be used to connect to any monitor that has DVI-D input...which most of them have had for a decade or more.
Also bear in mind that the VC4 that is in all Pi SoCs to date wasn't new when the first Pis hit the market in 2012. One may surmise that then next gen Pi (popularly referred to as the "Pi4B") will *probably* have sort sort of upgraded version of the VC4, as Broadcom has SoCs on the market with something that fits that description.
The real key to figuring out what is feasible on Pis is to look backwards, not forward, because at the Pis price points, up and coming tech is too expensive. I used to refer to building with that technique, "trailing edge technology".
