I find this to be a very frustrating response. I realize line 6 is in business to make money, but historically people retain analog guitars for very long periods time and I would think line 6's business model would hope people would keep their digital guitars for a long period of time. Part of that long term commitment is I spend my hard earned $'s to buy line 6 equipment and line 6 supports it for a long period of time. Line 6 has chosen to use the "personal computer" to provide a critical, highly marketed component (Workbench) of the variax guitar line of equipment. Changing/evolving operating systems is a given in the computer world that line 6 operates in. I am pissed off that 3 1/2 years after I bought my Variax 600 new, a critical component is SOL. I expect I am going to soon find out that my PodXT pro won't work with my MBP either. That is something I will explore at a later date. I have been a loud proponent of Line 6 equipment with everyone I talk to about music but this experience is souring me on Line 6. I wonder what the people who have spent $1.5K to $5K+ will think when in a couple of years down the road line 6 chooses not to support the operating system they are using for workbench!!!!
