Hi Mark,
As Shenkadere mentioned, the actual Harlequin portion has not changed in a very long time. However, if you add the Xitron workflow into the mix, the Harlequin interface simply becomes a configuration tool and you rarely have to work with it beyond setup. Plus, the workflow gives you clients that will run on Macs and PC's throughout the shop so you don't have to be tied only to the computer running the RIP. For what it's worth, the workflow interface in a re-design phase now, which will be the third since its introduction ten years ago.
To the happy users chiming in, thanks! I appreciate it. We're nearing the 35,000 RIPs sold mark.
