It's not the MO... it the unbridled enthusiasm for a piece of gear that we all KNOW he's going to turn around and stab in the back after a few weeks.
It's POSSIBLE that some people take Donny's recommendations seriously, and that just seems so irresponsible. How about waiting on the recommendations until you've kept something for, let's be safe and say six months..?
Don't take it so personally. Although you may not move through gear in the same way why do you even care let alone continue to whine about it on a public forum? Find a new outlet please. And changing a keyboard is not "stabbing it in the back". OMG keyboards are inanimate objects, you do know that ... don't you? Changing a keyboard simply means that something else may be better in some areas for your application it doesn't mean it doesn't have strong points. It is all subjective.
There are more important things to argue about. This just ain't one of them.
