Why Web Services

I have been reading about Web Services (SOAP, RPC etc) but somehow I am not convinced how the Web Services can be put to practice.
Most of the examples I came across are either Weather, Temprature, Currency , Airline Reservation etc., I dont understand the benefit in making these as Web Services.
Looking forward for your views on this

Am I getting this one right ???
For Non-Browser machines, if they want to get weather related information, it would be easier if weather.com had a web service running.
What if they dont have a web service running ?? Then I might be forced to use the URL object and what i would be ending up doing is parsing the HTTP response that I got from weather.com
2) Say I am hosting two websites from two different machines. One of the websites have Credit card interfaces in them (Using Java Beans). Now I would like to get my other website credit card enabled. How should I go about this ???
a) copy the credit card interfaces on the other box
b) Have a Credit Card Webservice on Box 1 and invoke that from Box 2.
c) I am totally wrong

One thing web services make easy is a customized "Portal". Suppose you want to let users create their own view of your web site by adding selected bits - for example, current headlines, weather, stock quotes, etc. - each of these bits can come from a separate web service source but be presented on your site in a coherent page, reformatted to your style.
It is sorta covered in the JavaRanch Style Guide.
