ARMv6 still? I don't see how that's necessary to save on the BOM. I hope legacy code was not the deciding factor here.
ARM11/(ARMv6)? I thought that core was a dead-end that was quickly replaced by the Cortex-A (ARMv7) series. Surprised to see ARMv6 in new hardware in this age...
Am I weird for wanting to use this for really simple web hosting?
What's the same: - Same form factor as the model B+ (your enclosures and daughter boards should still fit). - Same full size HDMI port - Same 10/100 Ethernet port - Same CSI camera port and DSI display ports - Same micro USB power supply connection What has changed: - A new turbocharged Broadcom BCM2836 900MHz quad-core system-on-chip with performance at least 6x that of the B+. - 1GB of RAM Source: http://raspberry.…

Backward compatibility is a smart move sometimes. All the users can swap their design with the rpi2 in place. A nice feature. I'm all for newer ARM ISA, but I can understand (after some HNer explanation) v6 can be desirable.
Anyone know where this can be purchased now?

EDIT: apologies, it looks like this link in fact contains the "old" B+ not the one discussed here, my bad.

AFAIK ARM ISAs are almost completely backwards-compatible so ARMv6 code should be fine on ARMv7; however, there does appear to be a few caveats: https://www.riscosopen.org/wiki/documentation/show/ARMv7%20c...

Why are they required to release those datasheets?
They're not, but it's been common practice in their industry for decades, and it's generally seen as beneficial to OEMs and users to have access to datasheets before purchase. This is why it's also commonplace for most chip manufacturers to offer free samples, even of chips upwards of $20 list price. Most of them even publish enough information to develop hardware and software to interact with these chips even withou…
