How often do you work offline without an Internet connection? We are becoming more tightly coupled to the Internet than ever before as the use of web applications continue to proliferate our lives. Whether it's an office application, calendaring system, email, or blogging interface we just can't live without them. The reality is that there are many instances where we might not need to be hard-wired through the Internet to work but just need the application and possibly a small set of data to do our job.

What does this mean for the web browsers we use? I stumbled upon a nice article that explains the current trends in browser and Web applications. In a nutshell, if I read the article correctly, our browsers will be getting a bit thicker in the not to distant future. Larger caches, some local application, a small database, and of course we will need storage to keep this local. There wasn't any mention on the amount of storage required but surely it can't be much. Just think of the synchronization that would need to take place. But if I look at my google calendar, there is about 200KB. Probably not too bad when you consider that only updates will be moving back and forth.
