Would you mind elaborating on this a bit?
I bought a Windows XP-running laptop in the summer of 2006, and it came pre-installed with Google Desktop Search. After a year of never using it, I deleted it, figuring it was just bloatware duplicating the Windows search function (which I’d never given much thought to one way or the other, but seems to work fine…?).
Possibly I’ve never used a really good search function and don’t realize what I’m missing?

The problem with the standard XP search function—the one you get when you go Start > Search > For Files or Folders) is that it has no proper indexing system, so every search is done pretty much from scratch. Not only that, the XP Search interface sucks, and its in-document text search capability has always been awful.
The difference with a proper desktop search tool like Copernic or Google is that it actually goes through your files when you first install it and creates an index. This index is created from words in the file names, as well as from words within documents (Word docs, PDFs, HTML pages, etc., etc.). The presence of a master index like this makes search functions much, much faster, because the search tool searches for your search terms in the index first. The index essentially tells the search tool which documents and files contain your search terms, and those documents and files are then displayed.
Also, the display interface used by Google and (especially, IMO) Copernic are far superior to the XP one, making it much easier to find exactly the document or file or folder you are looking for. Copernic makes it easy to sort your results by file type, date, folder, etc., etc., and i believe Google does the same. It’s just orders of magnitude better than the Windows XP search function.
Now, because these search functions create and use an index, they need to have a place to put the index on your computer. And because the index is a guide to basically every file on your computer (you can choose not to index certain folders, if you prefer) it can sometimes get reasonably large. My Copernic index is 1.4 GB. On most modern computers, though, that’s not large enough to cause any space or storage issues.
Also, because you want your new documents to be added to the index, the search tool should be left running (indexing) in the background on your computer. That way, whenever you create, modify, or delete a document, the search tool can make the appropriate changes to the index. I have my Copernic set to only index while i’m not actively using the computer (typing, browsing). That way, i don’t see any performance hit while i’m using the computer. If i leave the computer for dinner or something, Copernic will catch up on indexing while i’m away. It’s all really very easy to use.
The only thing you really have to wait for is the initial indexing. When you first install the program, it will scan and index your whole computer (or whatever drives, folders, etc. you want), and if you have a lot of files that can take a few hours. After that, though, it just runs in the background and makes searching much faster and easier.
Since i installed Copernic on our computers, my wife and i don’t know how we lived without it. And i have friends with Google desktop who say the same thing.
I believe Windows Vista has incorporated a proper, indexing search function that makes third-party utilities unnecessary, but i haven’t read any reports about how good it is.
ETA:
I should add that, if you don’t have many files on your computer, or if you hardly ever need to search for anything, then a fully-functional search feature might not be necessary for you.
