Maybe I'm in the minority here, but Wolfgang seems to have a very narrow vision. First, in the third paragraph he mentions smartphones and tablets, then puts this (iPad). The iPad is not a smart phone, nor is it the only tablet. I understand it is the most popular - so what. And why no specific smartphones named? Very narrow indeed. And please note, I don't hate Apple, I respect them - have to as my wife has a MacBook Pro, iPhone and iPad 2 to my Win7 laptop, smartphone (Nexus S) and Asus Transformer 101.
Then the article states,
Those of us who are 30+ years old will have to rethink the way we interact with computers.
Speak for yourself, and please don't brand me with your vague accusation that people over 30 have inflexible minds. I am way past 30, have worked with computers since the days of loading programs from cassette, using 8" floppies under CPM and have seen the changes first hand. I take these things in stride at worst, and when there is useful innovation I embrace it. As noted, I have a tablet and touch works beautifully for some things, but, as you suggest, it won't be the end all for user interface. I do a fair amount of video editing, and at this time, touch is too clunky to be really useful.
Then the article goes on a rant about germs, etc. Interesting, but it comes across as a bit obsessive compulsive. And as it notes, keyboards are already bad, but we manage to live with it.
Back to the narrow vision, yes, IF Win 8 forced everyone to use touch, it would die a necessary death. However, it will have room for both touch and keyboard/mouse. Will touch ever get so refined as to replace them? I don't know. I wouldn't mind if it did. But we need to read articles that see both the forest and the trees. Widen the vision a bit first, then the specific can be dealt with in a more informed and rational fashion.
