Desktop internal apps are a nightmare. Deployment is more difficult, it's harder to find developers willing to work on them, the only way you can access them remotely from a mobile device is using something like Citrix Server, the desktop management tools that you can use to deploy desktop apps are error prone, etc.

I said VC, but even as an architect of internal line of business enterprise apps, I would be kicked out of any managers office if I suggested developing a desktop app.

Heck these days it's hard to convince companies to write real native mobile apps instead of using one of the cross platform web based mobile app platforms.
