I find most people believe if a tech talks them out of new technology the customer more often than not thinks it's because the tech is incapable of supporting it.
I don't agree. If a customer believes that, it is because the tech didn't explain the situation correctly or has a weak/invalid point of view. I have worked with many technology retailers in my younger years, and new tech is not for everyone or even anyone. A customer that understands why new tech X-product is not for them will appreciate your honesty and will remember you for not selling them something they didn't need/want (even if they think they did).
I find that (In the case of Windows 8) all you have to do is let the customer decide. Half of my customers that ask about it have never seen or touched Windows 8, they only saw some groupies dancing around with "those tablets with the colored keyboards". Once I pull out a laptop with Windows 8 and let them give it a go the answer is "Oh, nevermind, I didn't know..."
The problem I see with Windows 8 is that is doesn't really seem to improve upon an existing problem that needed improving in the first place. Microsoft has so much invested in this platform that started with Nokia and Windows Phone/penetrating the mobile market that they are forgetting about their existing user base. Windows phone: Failure. Nokia lost over a Billion dollars last quarter with revenues falling 19%, selling 2.9 million Lumia smartphones. Fail. The market is speaking... and it is saying hell no to Windows Phone UI as it is now. Microsoft's answer? Let's make our flagship OS the same!

Meanwhile, Microsoft is out touting it sold 40 million copies of Win8, but wait, that's mostly to the OEM's, not the public. It's seen a slower or same adoption rate of 1% during the first month that the "problem and perception plagued" Vista saw in it's first month (horrible). Windows device sales are down 21% YoY with the Win8 release on Oct 26th.
Dell and Samsung are seeing weak demand.
Asus's CFO:
demand for its touchscreen PCs was low, and said, "Demand for Windows 8 is not that good right now."
Then you have Surface Pro that will be hitting the streets in January at $900. 64GB of storage and half the battery life of current Ultrabooks and tablets, keyboard is $100 extra. No chance this makes any big sales anytime soon.. and MS knows it as it cuts it's Surface Tablet orders in half to a measly 2 million units. If you want to run a business into the ground, this is a good way to start - Stop listening to your user base throughout the entire development process from user to developer... push everyone away to your competitors and offer a line of inferior products for more money all while shunning your hardware vendors of 20 years.
So, tell me, why should a customer think the tech is "incapable of supporting it" when failure of a large degree is almost assured on the part of the producer? If I was told that the HP Touchpad was going to be "the next big thing" by a Tech... then I would be really ******.
