Amiga & AROS Crisot has made available a new demonstration video (xvid avi mirror1|mirror2 MPEG1 mirror1|mirror2) showing the AmigaOS4-beta implementation of the unique AmigaOS feature, screen dragging. For recent user screenshots of the AmigaOS4 pre-release look here.

What about underlaying security models or are they just going to be another game console, even then they need security for online pay to play etc.

AmiSSL has been available for a long time, but what does security have to do with game consoles? This is a desktop operating system which happens to fit on an 8 MB Flash Card or fully read-only drives.

68k apps, really, Apple supports old CPUs via emulation or translation for how long, 4 years if that? How old is the 68k, please.

Thanks to this, AmigaOS4 can use hundreds (thousands?) of existing 68k apps and games, right here and now, right out of the box. Without this, the transition to PPC would be much rougher, maybe impossible and OS4 would have a much smaller userbase, simply because many older Amiga apps still are 68k. It's a fact that has nothing to do with age, but the amount of apps available for 68k.

Emulation is much faster than a real 68k processor, matching that of a 3-400 Mhz 68060 processor. It's there for compatibility and it's so transparent, that you won't notice whether its a 68k or a PPC program you are running, except for speed differences. It's also so finegrained that 68k apps will take advantage of PPC libraries, if they are present. This is possible, because emulation is handled at the kernel level.
It doesn't bog down AmigaOS4 at all to have 68k emulation, and all you'd get would be pissed off users, that can't run their favorite 68k apps, if the feature would be removed by release. Remember Directory Opus Magellan? That's still 68k...

Also another argument is that many core components early on were still 68k, such as the graphics library. Without that, it would have taken another 6-12 months before we would see the first beta! You need so many 68k elements that a 68k emulator is necessary. That's how OS4 ran early on. This is a very good testbed for the kernel based 68k emulation, so it could be tested, while components were ported to PPC. Quite clever, right?

This is much, much more advanced than what Apple did with MacOS8-9 emulation.

New apps are of course not developed for 68k if they are AmigaOS4 only.

What about IDEs for devs, anywhere I can find info on them?

Hyperion Entertainment has offered an SDK for AmigaOS4 since the first prerelease a year ago.

What bout endiness on the Amiga code? How portable is it.

If they wanted, it could probably be back-ported to 68k, but as far as I know, the code is big endian (PPC) dependant, but I don't know...

AmigaOS4 is way more portable than ever before, so if Hyperion finds time and money to port to a little endian platform, maybe that'll happen.

Can this run on Apple PowerPC laptops is what I want to know, if it can id go out and buy one for it, or Id wait for the price to drop as they migrate to Intel.

As long as Apple don't provide developer documentation for their hardware, it won't happen now.
