And forget the thought of making your LOB applications work in the "Modern" UI framework.
Where are the stock trading or ERP apps that really get work done?
If they want all us developers to move to that environment, where are the real productivity apps that we can look to as models? I'm really looking for answers here!
I don't get this. Metro apps were never supposed to be a replacement for "normal" desktop apps. They were supposed to regain ground from smartphones.
The only people saying that "Metro is the future" and the "desktop is deprecated" are people who haven't engaged their brain or have bought into a lot of FUD being slung around the Internet (there's a lot of people who construct scenarios whereby Microsoft "fails" just to revel in it).
Win8 still runs apps written for Win95. Apps written for the Win8 desktop will still work long after you have run out of customers for your current offering 10 years from now on Win13.
The reason Microsoft isn't talking about or providing huge support for LOB apps in Metro-land is because Microsoft don't think that LOB apps are a good fit to the metro model.
Metro is for games (like angry-birds), tablet apps (like finger painting) and for dashboards. The reason it's hard for you to move a 300-form LOB app to Metro is because it doesn't fit there, and nor was it ever supposed to.
The only market you lose by not re-writing your app to Metro is the tablet market. But if your app is almost certainly going to suffer and die on a tablet anyway (because it's huge, doesn't support touch and the whole design isn't tablet orientated) then you're not really losing anything by being unable to deploy it on WinRT - and even if you did care enough about that market, there's always the Win8 Pro tablets.
