I agree. Most of our RPis are actually running Debian, but in extremis
it's always possible to roll back to Raspbian as a baseline configuration.
There are of course other small boards: Olimex, Odroid and now Asus.
However RPi does offer a fairly flexible and cost-effective range, and
unless the OP is considering shipping hundreds rather than 10s of boards
I suggest that getting onto both the Linux learning curve and one for
minority hardware is quite simply not cost-effective.
The problem is that rpi has no fast storage interface (like SATA), some of
the more expensive orangepis have sata. (though I'm not entirely sure if it
is not bridged via usb)
A colleague's just pointed me at ongoing discussion of the new Asus
board, where somebody's observing that "OrangePI also offer a solution
with integrated bootable eMMC"
I had an Odroid/Hardkernel eMMC module fail a few weeks ago, and my
understanding is that I'm by no means the only person to have seen this.
I also believe that the manufacturer is keenly aware of the problems...
but at least it was a removable device and once pulled the board will
boot from SD-Card.
Being able to plug an ordinary SD-Card into a Raspberry Pi is definitely
one of its strong points. It's a bit unfortunate that it doesn't use one
of the standard boot loaders (U-Boot, OpenFirmware or whatever) but it
generally /just/ /works/, and it doesn't rely on having an onboard
component which can only be fixed by JTAG when it breaks.
Now one might argue that as long as it works or at least can be fixed,
the boot loader isn't relevant to something like FPC and/or Lazarus. But
I'm currently playing with an Arduino-compatible board hooked onto the
RPi's console port, and to get that working I had to change the kernel
command line: for an RPi that meant editing a text file, while for many
other boards it would mean updating Flash.
