Lots of software would be better (from the user's POV) as a desktop app. However as a developer and as a software business owner/investor, it's (much) better to write web apps. So it depends on what you're asking here. Should you invest in desktop dev skills to further your career? No. Should you write your software idea as a desktop app if you want to make a business of it? Not if you can avoid it. If you're asking something else, well I guess the answer is 'maybe'.
