I agree with what you have to say Adrian. I do also see systems becoming more integrated or a fusion thanks to wireless tech in homes and offices, as well as those that use the cloud to share information.
Eventually I think their will be an integration of todays netbooks and other mobile systems to the point a person doesn't have a home pc any longer. Just a screen, keyboard & mouse, printer and external storage devices. Granted, netbooks can already do that, but they are still limited to a certain degree.
So, are we eventually looking at a mobile phone with the power of a netbook that can synch with our other devices? I think that is where its headed.
Ways people access the internet are radically different than just a few years ago. Households without home computers or broadband get online via mobile devices (I'm oversimplifying for space constraints). From the New York Times, July 22, 2009:
"'The cost of broadband and personal computers drives some users to adopt mobile Internet instead of the traditional wire-line,' Mr. Horrigan said. 'It might make sense to invest the money in a smartphone and a monthly plan that enables you to do so many different things, like make calls and send e-mails.'"
"The heightened activity among African-Americans and English-speaking Hispanics helps offset lower levels of access to the Internet from traditional outlets, like desktop computers, laptops and home broadband connections. For example, an earlier study conducted by the Internet Project found that African-Americans trailed the national average in broadband access at home."
This doesn't take into account game consoles and other devices with smaller and more specific form factors.
You can add that some are using thier mobile devices as their access point to the internet for their laptops and home pc's. Though the cellular service providers frown upon it and most often have it set so the devices have that feature turned off, the ability is there waiting for the hackers to do their deed.
Using your mobile device as an access point for your laptop is a different animal. At that point you aren't using the mobile user interface, so the principles of mobile UX design no longer apply.
