Just put some pictures of the World of Amiga show online at http://www.ianstedman.co.uk/woase/woase2002.htm Not put a show report yet but I have added comment text to each picture.

The show was good from my point of view, got a few bargains and got to play with a few Pegasos systems. All of the companies present were doing good trade and had good offers

Apparently AmigaOS 4 is 90% done, just the last few bits to do. The last 10% is always the tricky part. Ben Hermann's who presented had a sense of humour with a few jokes about Amiga user complaints! ;)

Some techie stuff on OS4 while I remember, exec re-written in C taking 42000 lines of code? Context switching times of 4 microseconds on AmigaOne and 40 microseconds on Blizzard PPC. Compare this to 400 microseconds or more for OS X. Apparently gives better real time performance than QNX momentics!

Amiga OS 4 has new TCP/IP stack, support for ReiserFS and the old FFS. USB built in. Hardware abstraction layer working well. HDToolbox replacement with media support. 68K emulation on a 600 MHZ G3 gives equivalent performance to a 68060@50MHz.

Unfortunately there was no demo of Amiga OS 4.

Thendic came well prepared with many Pegasos systems running MorphOS, MacOnLinux and SuSE Linux. I was impressed with these systems.

Eyetech had an AmigaOne in an ATX case, a motherboard and a system sort of running. I say sort of as I never saw anything more than a boot console.

That is all I can remember at the moment. Enjoy the pictures. Overall the show was enjoyable.

In reply to Comment 27 (Davy Wentzler):
The drivers aren't a problem unless you're really overloaded and the user put the sound card on a low priority line. The driver gets an interrupt and has a chance to move data almost immediately in the fast IRQ handler, if I understand what you mean correctly (I've never written a sound card driver from scratch, although my next work may soon change that).
Yes, I was talking about pro software, sorry I didn't make that clear. You can run a Windows Sound Recorder type app (even one with multi-channel support) on any hardware and OS using huge buffers. Pro audio is a moving goal though, and I don't know what your software achieves but 5ms (256 samples @ 44.1) latency is certainly considered "annoying lag" even by semi-pro users.
Anyone reading this who's interested and has the equipment here's an experiment to try. Connect a mic and headphones to a decent desk with built-in delay effects etc. Disable any "bypass" monitoring and arrange for the output of the delay to be sent to the headphones. Set the delay for 0.5s or so and begin reading something. Hard isn't it! You are interrupting yourself and you're socially conditioned to stop talking. Now keep reading while steadily reducing the delay. You should find that at a certain point your mind accepts the delayed voice as "my voice" and you'll be able to read at a normal pace but you will still make a lot of errors because the aural feedback is delayed.
Now try with a guitar! It's like typing blind, your hands try to do the right thing but your brain is confused. Some people I've spoken to say they can't tolerate more than 0.5ms of software delay (the ADC and DAC cause additional delay) when playing a guitar with software FX.
