On First screenshot: Beagleboard runs RISC OS 5 desktop:

Without meaning to belittle Jeffrey's efforts, I think he's shown that you don't need years of experience of developing RISC OS 5 to be able to port it to new hardware - something that wouldn't have have had the same impact if one of us at ROOL had done the port.

That demonstration is really valuable, because hopefully it will encourage new developers to come forward, and so maybe, yes, we can look forward to having a wide choice of hardware on which to run RISC OS. We're already beginning to see the number of developers getting involved rise - and with luck it will keep on snowballing.

After all, compared to 10 years ago, or even 5 years ago, there is now a huge selection of ARM chips available that are capable of delivering a decent RISC OS experience - ARM's traditional embedded market no longer has to mean low performance.

On First screenshot: Beagleboard runs RISC OS 5 desktop:

Well personally I'm hoping there will be some useful boards based on the Freescale i.MX515 - a 1 GHz Cortex-A8 with built-in Ethernet and ATA controllers (noticably lacking from the TI OMAP3 that Beagleboard uses, and its OMAP4 successor), it's one step closer to an ideal desktop chip. Shame the video (as with most if not all of these chips, it seems) is still limited to 720p and no external PCI bus.

On Five tips for ROL over the next five years:

"ARM 6, ARM710, StrongARM, ARM9, ARM7500, VRPC and RPCEmu"

I really hope that you don't consider this a demonstration of portability. And even then, if you want to draw up a list of CPU core compatibility, I think you'll find the Pace/Castle fork wins. From the list in the sources:

ARM 600, ARM 610, ARM 700, ARM 710, ARM 710a, SA-110, ARM 7500, ARM 7500FE, SA-1100, SA-1110, ARM 720T, ARM 920T, ARM 922T, 80200, 80321, Cortex-A8

Or in terms of CPU architecture, your supported list is

ARMv3, ARMv4, ARMv4T

whereas Pace/Castle support

ARMv3, ARMv4, ARMv4T, ARMv5TE, ARMv6, ARMv7

But as I'm sure you appreciate, this is only a small part of the story. Granted, you have support for the ViewFinder and the Omega graphics chip, but at least as much effort goes into driving the rest of the I/O system, of which you only appear to support two varieties, IOMD and S3C24xxx (and even then, apparently, tragically, not via a unified source tree).

By comparison, the Pace/Castle fork has support for at least 7 (that I know of) radically different I/O architectures - not counting support for complex external silicon like Chrontel, DENC, MPEG or audio CODEC chips. And the HAL was designed as a separate binary component to enable OEMs to write support for their own I/O chipsets without having to pass the source back to Pace, so there may be others that I've never seen.

On Work starts on a RISC OS 5 ARM Cortex port:

The guys at TI openly admit that they're going head-to-head with the Atom and that performance is comparable. And I don't think that was including the grunt of the integrated DSP - for which many codecs (at HDTV level) are already available, including MPEG-2, H.263, MPEG-4, H.264, VC-1 (which encompasses Windows Media), RealVideo and VP6 - potentially these could all be made to work with RISC OS, and haven't we been crying out for that for years?

Maybe dual core Atoms are due out soon, but there are also multi-core Cortex-A9 chips in the pipeline too. Not that multi-core would be of any great benefit to RISC OS, of course.

I did say "most", not "all". :)
