DIGGINESTDOGG  I am a long-time user of OG product (Focus, Graffle, Outliner)--Outliner and Graffle through several versions including upgrading to pro from the standard versions that came with my Mac 3 or 4 years ago.

But having paid the upgrade to 4 Pro only a year ago it seems I am balking at the stratospheric price of this one. The upgrade is twice as expensive as it needs to be for a great app I don't use daily. For example: Illustrator, clearly 5 times the app OmiGraffle Pro is, is $199 to upgrade from CS2 to CS3--5x the app but 2.5x the cost to upgrade. As I said--the OG 5 upgrade costs twice what it should cost.

This is where I stop patronizing Omni products I think. I'll stay on 4 and start evaluating a migration strategy and course.
