No in both cases you are searching for information. Be it on the net, on your local hard drive, your e-mail, your AIM client logs, your pictures, your well you get the point. If you are looking for information on something it doesn't necessarily mean that its always on your desktop or its always on the web. As the speed of the web increases, and hard drive sizes explode in size expect that the differentiation between local information and information out "there" will become fuzzier and fuzzier. This is why Google is in a mad dash to get there first. These kind of technologies do have the power to topple Microsoft. Its the browser wars all over again but this time around its through search engines. Google has a major leg-up over MS, yahoo, and even Apple for now. The desktop engine they threw out is beta and a crappy beta at that. Its incomplete at the moment. But its intention was clear. It was a direct shot off the bow of Microsoft that we are there now.
Dont get me wrong. Apples implementation looks solid but its limited in the scope of what it can and will do. (Unless then make changes between now and Tigers release.) Apples spotlight feature is like fishing on the shore. Googles is still in the bay trawling with one huge *** net that isnt fully deployed. Once they get out to sea well. One fishing rod vs one big old trawler.
