[quote]I understand that backward compatibility is very important[/quote]
Only to those people who looks backwards.
To people who look forwards 32bits is not the future.
An A35 Armv8 with NEON in Zero or A+ form is forward thinking.
It makes sense for those teaching ARMv8 64bit and NEON.
It also runs at half the power? 90mw at 1GHz? < 40ma, that Arduino country.
Looking backwards from 10 years when 80%? of Pi's are 64bit and forced to run 32bit OS's.
Ignoring the 13Million installed base?
Well how many are 64 bit now and could run faster with 64bit OS?
3-4-5-6-7Million Pi3's are being ignored? Pi2 is 64bit now.
Actually I don't need a 64bit OS as I am moving to baremetal ARMv8 + NEON.
I just need ARMv8 Zero's, A+, B+
Single or even dual core would be ok.
The industry is well on it's way to doing mainstream 64Bit OS's for Pi's anyway.
While a 64bit Raspbian would be nice for developing AArch64 stuff, there are painful ways around it.
It will happen anyway.
RPF may have their fingers in the dike at the moment.
but probably in the background they are running around with sandbags or just swapping the wellies for waders
Backwards compatibility for Education?
Well how much penetration does RPF have in the Education market?
Mainly UK and early adopters in other countries. <0.1% of world schools?
How many of UK schools are using Pi and how many actually care about 32 or 64 bits?

[quote]A four-core SoC would hit 1.0GHz and consume 90 milliwatts.[/quote]
What 4 cores for 40ma
Single core A35 Zero 10ma?
Nah, give us 4 core Zeros,A+,B+
Die size A35 single core is 0.4mm sq, that's small..
Small die, cheaper/higher yields, more cpu's per wafer
Down side, software guys stay busy.
BCM2835 with 28nm A35 quad core, cheaper?
I see numbers that match 28, 35, it's destiny
