Google Voice has so many features that we've barely scratched the surface of what it can do. Is it worth trying? Absolutely. Since it's free, you've got nothing to lose by giving it a whirl.

Overall, this early preview version of Google Chrome for Mac looks and feels just about right, although it has quite a long way to go before it can make it mainstream or become your default browser. Keep in mind that this version is not for general use.

Google Sketchup Pro recently jumped in price, but while it may not be quite the bargain it once was — and while some of its functions are clearly more for CAD than digital content-creation — there’s still much here for 2D and 3D artists.

The latest update to Google Mobile App brings with it a party trick that is sure to get everyone excited at first. But after using it for a while, Voice Search is not particularly useful except for wowing friends.

Google Android is an exciting development in the world of mobile operating systems. It's not so much what it can do right now, as what the world's application developers can create when they get their hands on the code.

If your business uses Google Docs, and you have ever wished that something similar to YouTube existed for business use, Google Video for Business should suit your needs nicely.

Google has produced an excellent browser that is friendly enough to handle average browsing activities without complicating the tasks, but at the same time it's powerful enough to meet the needs of more-advanced users.

Google Mobile App is a simple search tool that relies on Safari for most of its work. If you regularly use Google when you are out and about, then this may be worth a look, but for most iPhone users, simply searching Google via Safari will suffice.

It is almost unfair to review the Google App Engine when it is just a beta operation, but Google has a habit of leaving some tools in beta form for a long time. There are a number of places where the documentation and the code suggest that Google will add more functionality pretty soon. The basic framework and the database are both quite nice, although limited. We can imagine Google adding better automatic features for generating the CRUD (Create, Update, Delete) routines common in these applications. Integration with Google's Wallet might also be quite useful, although it's bound to be complicated by the banking system. Some people have already experimented with mapping the Google Web Toolkit to the system, even though that's written in Java and translated into JavaScript. Google might also provide some good tools that allow the different hosted applications to share user information, in essence allowing a user to move their preferences and some of their data to other applications. This kind of inter-application linking could be pretty cool. Time will tell what Google delivers. In the meantime, this is a good sandbox for playing with simple database applications. There's a very good reason why the beta version has a waiting list.

The Android SDK is a wonderful example of what can be done with open source applications and tools. When the SDK's parts work, they work reasonably well. However, at this point, would-be Android developers must be willing to assist in debugging the development platform itself; it's still pretty rough. Android's single best characteristic is prime mover Google. Whether that is enough weight to ensure Android's success remains to be seen.

Google Docs' presentation tool is, ultimately, a rough draft that thoroughly deserves the beta label. Google reportedly plans to beef up the editing tools, eventually turning Google Docs into a richer environment. Judging from the slow-but-steady progress of Google Docs' word processor and spreadsheet, the presentation features probably won't acquire PowerPoint-crushing sophistication any time soon. That said, Google Docs should become only more useful over the coming months and, in the meantime, a lot of people are going to find it very useful indeed.
