If you want to pull your hair out and be frustrated by the tediousness of it, and how much longer it would take you, go for it.
Anybody who uses their work issued computer to do personal stuff on and stores personal stuff on it is naive and well, stupid. I used to work in corporate IT. Clueless employees would sync their phones to their work computers and then get pissed when we would tell them we were NOT responsible for their personal data (music, photos, whatever). Their machine crashes, "can you recover my personal stuff?" Ummmm...NO! Idiots!
You don't seem to have come across websites that *don't* work the same on a mobile device as they do on a desktop/laptop. Trust me, they exist. It's not just about rendering and how they "appear" it's about how they *don't work* properly.
I was not referring to people using work computers for personal, although that does happen often, but that those who content create do so mostly for work. So if you work from home, you would have a desktop, if you work from the office, you would use the office computer. The point being, more and more content is being consumed by most users rather than created. In those instances they need to create a document, they either use their older desktop (as pointed out above) or make it work on their tablet.
No, I have not come across a website that does not work on a mobile platform, please provide URL.
Lastly, and my mistake for not pointing this out, computer sales are down; this by no means suggest people are tossing their old computers out. The tablet market is booming. This suggest people like the portable aspect of the iPad. They can sit and watch tv while posting on Facebook. So the trend is to not upgrade your desktop, but rather purchase a tablet.
Once your can dock your tablet to a larger monitor with ease, desktops for the home will all but die. As then you can purchase one larger, better monitor that many can dock into when needed for those occasional content creation needs.
Content creators, geeks, gamers, techies will all buy what they will buy, but the majority of the world does not need a desktop for 90% of what they use a computing device for.
Those that keep denying this are probably those who said tables were a fad and no one would buy an expensive iPhone (because it did not have a keyboard), and so many others blind to moving technology.
I would love to see Apple quickly release a way to dock your iPad to a 27" Apple display.
