The screen on the Cisco isn't very big, either--192x96 or so, if I 
remember correctly.  I'm running 6.3 on my 7940, and I haven't seen the 
ability to do anything interesting with ringtones.  In theory, you can 
feed new tones to it, but you can't use them for ALERT_INFO-driven 
distinctive ringing.  The XML support is okay, but rumors suggest that 
the newest Polycom firmware supports something very close to XHTML, 
which would be a lot more powerful then Cisco's sparsely-documented XML 
dialect.

I don't think it can do that.  You can set ALERT_INFO in Asterisk to 
Bellcore-drX, where X is 1..5, and the phone will ring slightly 
differently, but that may or may not be good enough for your purposes.

MWI works just fine on the 7940, so I'm not sure that I'd count that as 
an advantage for the Polycom.

I haven't seen a Polycom in person, but I haven't heard anything bad 
about them.  My 7940 works well, and I wouldn't hesitate to recommend 
it, but for the money, the Polycom is quite likely a better phone.  I 
didn't find the 7940 to be particularly difficult to configure, 
*EXCEPT* for the initial installation of the SIP firmware.  It's a 
multi-step upgrade, because you can't directly upgrade from the SCCP 
image that it ships with to a modern SIP image.  Once you get past 
that, it isn't too bad, particularly if you have multiple phones.
