True story:
I have a friend who went into a heated discussion with me some time ago about how he thinks that phones and tablets will make classic PC obsolete and how they will stop making PCs because nobody will need them anymore. Him not being an technical or IT person, I made a mistake to try to explain him few things. He persisted that he can do everything on his tablet that I can do on my PC.
Few weeks later he came to me with a fancy expensive tablet and showed me how he can do this and that.. So I invited him home and show him PCB CAD. and this, and that, explaining that those are things I do on my PC and that he can't do that on the tablet.
After few more weeks he invited me to his place to have coffee and to show me something..
When I came, he explained to me that he was thinking and that he decided that I was right that he cannot replace a PC with THAT tablet he got because it wasn't good enough. And because I showed him what I do, he went and got a good tablet that CAN replace my PC in EVERY aspect.
So we are going into his home office. And there on the desk was most expensive MS Surface with docking station, 27" monitor, keyboard, mouse....
And then he went on that I was wrong and that he proved how tablets make PC obsolete.
After I explained to him is that a computing unit, that is Intel based, runs full windows, has 27" monitor, keyboard, mouse IS full blown PC, he was little confused..
And after realizing that I payed much less for my PC + Android tablet than he paid for his "one tablet to rule them all" he was confused even more.
So yes, people are irrational..
