See the post comments for an on-average ambivalent response -- go figure...
Do your Notes apps make use of much OLE embedding? If so, how numerous and/or important are these apps?
Does you organization make use of the embedded MS word editor?
I ask this because the user experience with any embedded OLE object will be different in Notes 8. Specifically, INSTEAD of in-place activiation,
creating a new document or clicking on OLE control causes full client (Word, Excel, Paint, etc.) to launch.
