[Evolution] IMAP vs. POP

[Bart <montana_evolution_user hardinmt us>]

Hope this is not too far off topic.

I am using pop for all my email accounts.  I receive all my mail on one
machine at one location.  But I keep seeing remarks that indicate IMAP
as being just "SO" much better.

Would someone either explain or point me to a place where I can learn
the reasons for these comments?
