I have converted quite a few to Resharper recently. I'm quite the addict myself and I can't see myself using Visual Studio productively without it anymore.

Resharper does have a learning curve however since there are just because of the sheer amount of enhancements it brings to working with VS.

To get you up to speed using Resharper, perform these settings in Visual studio after installing:
Within Visual studio: ALT - R - O => intellisense, completion behavior =>
Automatically show completion list in 0 milliseconds
"Check" all options except Case-sensitive prefix matching
Finally, "Only those that are at least": set this to 1

You can watch the following screencasts:
- James Kovacs screencasts on Resharper
- My own MVP coding demo using Resharper and Rhino mocks
- Ayende demoing Rhino mocks

(pls note that you'll need the Camtasia TSCC codec to view the last two)

You can use keyjedi to display the shortcuts used when someone else is looking over your shoulder. This will greatly enhance the introduction within your team. This only works on x86 systems, I have compiled the code into an x64 assembly that works on my win7 machine, let me know if you need it.

Lastly, have the developers print out the Resharper keymapping (in plastic cover preferably, in case of any coffee, tea and all that )

If you have any further questions, please let me know.
