most important desktop application: web browser
With a web browser I can do almost everything (if not everything) I currently do using licensed desktop applications.
I can create presentations, documents, and spreadsheets. Additionally, I can even store (and share) my files online. I can edit photos, video and music. I can email and otherwise communicate online. I can even analyze data.
Not to mention the additional things a web browser makes easier:
- Sharing: instant access, always available
- Portability: all that is needed is a computer (any) and an Internet connection
- Collaborating: through comments, simultaneous editing, etc.
Now, I know this wouldn’t work for power users, but in a short time I’m sure functionality will be added to each of these tools and bandwidth / processing power will make it possible for power users to be fully satisfied using these online tools.
Additionally, the web browser allows me to watch TV / video and listen to music / audio.
Thus, the web browser is by far the most important desktop application.
