Larry Seltzer has a good piece on why Google Desktop Search Doesn’t Threaten Security. However, I’ve found that Google Desktop does threaten one thing: my sanity. It’s the first piece of software I’ve found in quite a while that can reduce the performance of my laptop to a crawl at a single stroke, thanks to its large-scale background activities.
Of course, my laptop isn’t all that powerful – a 1GHz Centrino with 512MB of RAM. And of course, it’ll be better once it’s done all the necessary indexing of pre-existing files. But on a laptop, I don’t want to leave it on overnight to do it. So, for me at least, it’s bye-bye Google Desktop.
