1) After submitting a form, you are usually taken to the result at its 
normal viewing url (e.g. node/123) rather than the form's URL 
(node/add/page or node/123/edit). This makes URLs more consistent.

2) Any changes made to already-loaded Drupal pieces (e.g. the menu, the 
modules loaded, cache, the form itself, ...) will take effect immediately.

3) You can refresh the result without resubmitting the data (this used 
to be a huge problem on Drupal.org even when we were small).

4) You can provide permanent GET URLs for forms that are used for 
browsing only (e.g. search).

The amount of work duplicated is not as big as you seem to think. The 
POST request only deals with submitting the data and saving it. The GET 
request afterwards only deals with loading the data and displaying. They 
are mostly complementary.
