asterisk users - Sep 2008 - OT: real 2 line phone vs. 1 line and call waiting

I'm looking into getting a new phone and wondering what the difference
in functionality is between a single line phone with call waiting and a
real 2 line phone (either a real SIP phone or an analog 2 line phone and
a 2 port ATA) is.  Why would I want the real 2 lines vs. just being able
to take an incoming call via call-waiting?

Cheers,
b.

1) a two line phone can register with two different * servers or sip 
carriers.

2) It's easy for both incoming and outgoing to separate business from 
personal calls. (ie line1 is personal, line2 is business)

3) It's easy for a two line phone to register to two different accounts 
on * and then subsubscribe to two different MWI's on different VM 
boxes(again goes back to seperating business from personal or your VM 
from your significate other's VM)

That's just off the top of my head.
