We have three computers in our household: one desktop and two laptops. Right now, I'm on my desktop with two wide-screen monitors. Every inch of real estate is covered in applications.... all web-based: - Gtalk and Skype - Gmail - Google Docs - Pandora - Dropbox - Twhirl - About 15 tabs within my browser (Chrome)
My computer usage is entirely online - from content to applications. In fact, the only three programs that I use on a routine basis that aren't web-based are Adobe Photoshop, Microsoft Powerpoint and Microsoft Excel. There simply aren't powerful enough equivalents at this point. And for every PSD, PPT and XLS file, I move it between computers via Dropbox.
Here's why this is important:
First, while I am not the typical internet user... this is occurring more and more frequently. For me it started with smaller transitions such as from Microsoft Word to Notepad and Notetab... and from those two to Google Docs.
And it's not just the consumer: corporations are also making the shift. Supposedly one-million companies now use Google Apps. At Widgetbox, we are one of those companies. We also use web-applications to track our product process, backlog, QA, business development flow, and so on. It's a remarkable movement.
I think the shift (for consumers and corporations) reveals as much about portability as it does about lightweight, comparable functionality... which when combined, allow me to access content and applications on lighter-weight hardware - such as my iPhone. And this is precisely why the iPhone, the iPod Touch and Netbooks are the future of computing: I don't need a huge processor to do my day-to-day work. Rather, I prefer portability and form factor.
The only thing I need is visual real-estate. If I could my monitors into a netbook.... I'd be more than happy.
