There is a potential upside to this. Perhaps now certain application developers - I am looking at YOU, Mozilla and Oracle - will stop developing their stuff primarily to work with Gnome. I like using Netbeans, but I don't like the lag that gets added when running it under KDE.
I left Gnome behind years ago. The app suite was too immature, there were large chunks of functionality that were simply missing, and the apps that were there had a surprising number of bugs. I moved to KDE and got a much more feature-rich desktop. The widgets and apps that I needed were available, functional and highly customisable. Pick pretty much any task and compare the common Gnome app with the KDE one, and the KDE ones are usually far superior.
