Google is starting to become the new OS for most of us in this Web 2.0 world. Not only is Google one of the best search engines in the world (and I don't just say that because it is from my home state of Washington - or because the guy I grew up next door to works there or anything), but they also offer some very powerful tools. Some of my favorites are:
G-mail (I mean who doesn't love free e-mail that has unlimited space)
Google Calendar (it takes uploads from iCal on a Mac - how cool is that?)
Google Earth (which now includes maps of the sky)
Google Reader (which acts as an RSS aggregator - basically a reader of all of your feeds - I still am attached to NetNewsWire, but this is tempting)
and Google Docs, which has just added Presentations. Although SlideShare is awesome in its ability to post PP presentation. The power of Google Presentations is being able to work collaboratively on a document. It takes a page out of a wikis book and takes it a step further, so instead of a webpage at the end - you get a presentation!
I hope to do my presentations for NCETC this year in it and demo how it works! Come to think of it, maybe I should have a Google Session? Or is that Patrick Crispin's territory?
