As somewhat of a power user when it comes to computing (I'm a software engineer, it comes with the territory), I find that I really dislike most web apps. While some (such as GMail) offer keyboard shortcuts and other power-user-oriented treats, I find that most web apps are largely point and click with a lot of separate pages. I definitely feel a lot less productive when I am forced to use a web app for a certain function, and will always look for a desktop application or mobile app alternative whenever faced with the scenario.
However, I'm well aware that my sense of productive impact may be skewed, personal, or just plain incorrect. So my question is:
What impact, if any, does replacing desktop applications with web apps have on productivity?"
Update: I appreciate the answers I've gotten so far, and I do think this is as much a personal matter as it is any kind of universal question, but I would also love to see answers that provide things like statistics, studies, surveys, or other more empirical measurements of the changes in productivity brought on by using web apps.
