I hear ya, but what is the ongoing cost of support, programs, etc.....that's the key, I think. If they have to deal with spam, viruses, bugs, gigantic upgrades, purchased programs, etc. the costs of ownership add up (along with the frustrations)
And what does it weigh? Big diff between less than 3 lbs and 5+ pounds......
The complexity of any full OS is for those who need them. As we have seen with the phones and tablets, 90% plus of the population has declared they don't need them. The laptops and desktops are the next and final frontier, IMHO. I doubt apple is selling many Mac Pro's these days. I have my 5 year old model (8 cpu's) and can't imagine why I would need faster. In fact, if and when it breaks down I'll prob replace it with a fast mac mini.
I remember back in 1996 when Sun was pushing for the first network computers - they were what the new Chrome stuff is today, but of course not as a fast and wireless was not as popular. It took 15+ years more, but I think we are about there! Now people just have to understand their needs a bit better.
Only a few short years ago, the world was pooh-poohing android. Look how that is turning out!
