Edit (6/1/04): I decided to make a better toolbar that all the others out there. They all want to promote their searches and we decided to make one that searches them all.

Search the Web and other resources directly from your toolbar.
Learn about Web sites including traffic information and contact info.
Surf more efficiently with Related Links for each page.
Share opinions about sites with other users.
Alexa (an Amazon site) uses google to enhance it's search features. Its unique feature is that it contains user submitted reviews and traffic analysis for most of the internet. Sites are rated in order, e.g. yahoo is number 1 (in traffic) google is 5 etc.
Alexa collects your surfing information in aggregate and it's from this data that the traffic is reported.
It automatically shows related links on the toolbar and you have one click access to dictionary and thesaurus look ups. You also have one cleck access to Amazon (it's parent site) and news sources.
Their traffic data is imperfect but the best available on the net. Sites with older demographics are less likely to ahve high traffic rankings. New sites (less than a year if they are not large) are a bit weakly represented. Some Korean sites are very hightly respresented and sites related to Alexia like Amazon are a bit too high (because of the fact taht Amazon visitors are more likely to discover the tool bar and therefore they are dispoportionately represented by the tool bar stats.
Some users will like their popup blocking capabilities.
Note to webmasters: Using the tool bar will of course, improve your traffic rankings. Alexa uis a good site to use to investigate backwards links. It takes google results and filters them in a way google doesn't.

Google's toolbar also reports browsing behavior unless you choose to not send this data in exchange for less features (mainly no pagerank data is displayed for the site).
Google toolbars can open searches in a new window. They display a web page's category in the dmoz directory and show it'pagerank (the way google values the weight of a page). The search words are passed to the toolbar and clicking on them after a search will perform the CTRL + F function on the page. Making it easy to locate your keyword in a big document.
Google has one button access to it's news services.
----------
In deciding whether a toolbar is worth it you need to ask yourself whether the features available on their sites (all the toolbar features can be used from their respective sites) are good enough to want instant access to them. Google works well as a spell check and a search. Alexa gives information about the sites you are visiting that you can't get elsewhere.
Ultimately it's up to you whether you want them at the top of your browser. If you install them you can easily toggle them on and off.
You can use both at the same time if you wish.
What other toolbars do you like? Yahoo has one that is good for anyoe who uses yahoo's services like email IM etc.
