Wayne,
First of all, let me say thank you for keeping Amiga.org going all these years, when people ask me for sites for info on the Amiga, I tend to mention your's, sometimes before Amiga Inc. own site.
Though I'm not quite sure where you're going with:
"though I firmly believe their continued existence will eventually be the death of this community. "
If I follow that logic, it seems like we should, either, quite while we're ahead and become Linux-heads (that's basically where I'm drifting) or start signing up for Retro-computer shows and hanging our with the 8-bit Atari crowd telling stories about how we would have done things if we'd been running Commodore or ogaling AAA specs.
At some point, you have to move on. Me, I went with AmigaDE becasue it chance (maybe a slim one) to make sure PDAs don't turn out as boring as desktops did. Now as far as desktops go, I like what they're talking about, can they do it? I don't know, but I do know that at least they are thinking about more than cloning the WindowsXP interface. Will they do it? Maybe, but, then again I look over at what Bill Buck and the ex-Phase5 guys are talking about and it's not much new either.
At some point, you have to pick at a few long-shots, you might as well go with one that is looking forward and not sideways.
