Ravi,
What us Open Source evangelists are missing is an honest comparison
between ESRI desktop applications and Open Source equivalents.
What is it about ArcView and ArcGIS that people really like, listed
feature by feature in a table.
Then identify whether Open Source covers it and how.
Very important is to address usability. How quickly can an Arc* user
migrate to Open Source?
My skill set is lacking here as I don't have much experience in either
ESRI or the Open Source desktop tools. It seems like you have experience
with both which puts you in a unique position.
Is this something you, or one of your students would like to investigate
further? Maybe build a table similar to this one:

Hi,
this is the kind of question I face when in my lectures evangelising
OS GIS.
ArcGIS has many tools, though some prefer to call it a deluge of
tools, which almost distance the user from understanding the concept
of GIS.
Auto Complete Polygon:
In Qgis which is a very userfriendly OS GIS you have 'Cut polygon', do
try and find the difference.
Polygonising from lines:
Open JUMP has one of the most userfriendly approaches.
Create lines and polygonise in OpenJUMP and the software automatically
creates a folder for Dangles (un-wanted line pieces)
The query is more for Vector GIS, I suppose.
GRASS GIS:
It has so many features for Image analysis and Raster GIS, the
commercial GIS need a barge pole to even touch it. The vector Part of
GRASS is robust too.

We are working on that:
http://grass.osgeo.org/wiki/WxPython-based_GUI_for_GRASS#Digitizer
Screenshots:
http://grass.osgeo.org/screenshots/gui.php
-> wxPython (new GUI)
You can try out the prototype in GRASS 6.3.0 (released yesterday):
http://grass.osgeo.org/announces/announce_grass630.html
Get MacOSX, Linux and now even native MS-Windows binaries with
*installer* at
http://grass.osgeo.org/download/index.php#g63x
Enjoy
