johansch, you were wrong in such a fundamental way about this subject that it is hard for me to believe you know anything about it at all.
If you have any suggestions about how I can phrase this in a way that makes you both comfortable, and that still makes it clear that I do not believe you have any business speaking on this subject, then I am 100% happy to listen to you. :)
I'm sure you're otherwise intelligent, but this is an area where you should probably just listen.
$10B are spent each year on sales of actual mainframe computers. [1]
The article quoted in the last article claims that everything you sell around mainframes, like services, is a quarter of revenue.
Now, it's your turn to do something for me. Don't respond if you're not willing to read before you speak. I should not have had to explain this to you.
