P100 with 32mb of RAM is the practical minumum for acceptable everyday 
performance with modern apps like mozilla and OO.o . A 100mbps NIC helps 
a lot for occasional full-screen redrawing and display of huge images, 
but otherwise isn't needed.

The biggest problem with 486s though is the video cards - 800x600x8bit 
if your're lucky. 8bit colour with modern apps is really nasty - I think 
a reasonable minimum is 1024x768x16bit . OEM P100s are usually great in 
this regard, as something like 90% have an S3 Trio32 or Trio64 chip in 
them which matches the video requirements quite nicely.

The flash issue was fixed a fair while ago with the release of Flash 
Player 6 for Linux. It was a macromedia bug and they'd been stonewalling 
for 2 years... *sigh*.

I haven't had a problem yet, and I use a P100 diskless LTSP workstation 
as my primary machine now (the old dog food technique).

Also, to be honest I've found OO.o's PowerPoint compatability much 
better than its Word compatability (which I think is rather poor). OO.o 
has a /lot/ of problems handing Word documents with very complex 
formatting and layout. Working at a newspaper, I get a lot of those, as 
you'd be amazed by the number of people who think that Word is an 
acceptable desktop publishing program.

That said, our app set:
Red Hat 8.0 running DHCPd, tftpd, gdm2, etc
Mozilla 1.3 (xft RPM build)
OpenOffice 1.0.1 (built in to RH8)
IceWM 1.2.7 (customised theme and config)
Rox-Filer 1.3.8-1

works really nicely. I have a few reliability problems with mozilla that 
I'm trying to track down, but other than that it all runs great.
