On Morphos-news, there's a nice ARC report, including this tidbit: "The release of the G4 CPU-boards is planned for the end of January - and for this event there will be a limited number of Pegasos-computers in special cases." :) Martin adds: Furthermore there's a more general text for people not familiar with the Amiga market about what Genesi, Pegasos and MorphOS are about. Since my English is very bad and very much "german English" - especially since I wrote it in Aachen -, I suggest that if you are able to understand German, you better read the original version.

You should stay with your A1200 as long as you are satisfied with it then, but
a lot of us want new computers that carry on the tradition.
As for those graphical demos, I think they are very math intensive and you
could never run more than one of them on an A1200. But this should be easy to
test, if someone compiled a version for 68k? Heck, maybe you could try running
the version supplied on the MorphOS CD.

Hm. Well I don't want to be rude to the author of those demos, but
I've seen them too and I think it's obvious that they aren't as well
optimised as we're used to with Amigademos. That is, they take up a
lot more CPU than they look like.
Anyway, the mouse does slow down on the Pegasos when it puts out debug
output over the serial. So I guess this is one more good reason to
turn this off during presentations. Apart from this I haven't noticed
any mouse slowdowns even under heavy load. There shouldn't be really
since it's the same kind of priority-driven cpu scheduling, and the
mouse movement has a high priority. So unless something with even
higher priority suddenly takes lots of CPU (which shouldn't happen)
the mouse should never slow down.

In reply to Comment 52 (Johan Rönnblom):
The mouse pointer on classic Amiga is a hardware sprite and thus the cpu isn`t involved(or hardly?) in the process drawing it etc. So afaik only interrupts can cause the pointer to lag and be jerky. On pc(and thus pegasos) gfx cards nowadays there is 1 hardware sprite(2 colours mostly) for the exact purpose of making the pointer. So normally it should then be as smooth as on an Amiga. The jerky pointer one could see on older pc`s was caused by the fact the pointer was rendered in software rather than hardware.
Correct my if I`m wrong though :-)

Here's a translated version into English via Google. Which actually makes sense (Sort of!)

The jerky pointer was caused by the serial port mouse.
