Well, as something that's been on my eventually to get around deciding; I've setup Google Desktop Enterprise Edition on SAL1600.
Earlier during the last reformat, I had opted into trying a newer Windows Desktop Search, yet found it to be just as useless as the old style search technology that had shipped with Windows XP back in 2001 :-(. In point of fact, I would much rather use GNU Find and skip the useless window dressings >_>.
Googles Desktop search, is not what interests me. In fact, nether does Strigi or Beagle - the only search program that would interest me, is a sexy wrapper around GNU Find (or equivalent) that mates it to a easily scriptable plugin system (think customized grepping) that would enable it to be come aware of any program you choose (think searching chats for pidgin, docs in google, news feeds in pan, blah blah) without having to rely upon someone to code it for you—just write a little shell script ;).
So obviously, I'm a power user who learned how to organise file systems very tightly, although I think that will become a mark of the dinosaurs before Windows 11 >_>.
What did attract me to Google Desktop, is the Gadgets system. Right now I have the sidebar up with time and temperature—never turn the TV to the weather channel lol. Since the only use I really have for Windows main panel, is the integrated system tray and clock, I've now set the panel to minimal height. I run much to many programs to be able to use a "Taskbar" without feeling like I'm dancing with a cement kimono!
The sidebar from Google Docks is also displaying Calendar & Mail gadgets making my life easier, plus Talk is docked for extra value. Since my desktop is never free of having a command prompt and web browser open, the Win+G shortcut for the search bar doesn't matter any 8=). Ok, so I'm a whore for tools that speed up my work time instead of increasing it ;).
Intently interesting me, is whether or not the deskutils/google-gadgets port on FreeBSD works reasonably. While Google Talk lacks a version that'll run on BSD, I don't need it—since I rely upon Pidgon, and wish I did not need Xfire on the windows machine.... since integration would make life easier. It's so funny how I actually have a more integrated system under FreeBSD, then Windows <_<.
OSX, KDE, and Vista have made greater emphasis on the desktop widget/gadget concept in recent years, but to me, it is just very much the modern incarnation of the old as gold dockapp.
It's so funny how new innovation is often an upgrade to the last generations revolution.
