You talking about the Mid-2014 MacBook Air not having any cooling system or the upcoming, rumoured one?
Haha yeah, I think he meant the rumored fanless design MacBook Air. In Apple line of products, rumored products usually comes true.
That's why I don't feel that much excitement when I watch the Keynote or Apple product launch events
But about shorten of lifespan because of fanless design, I don't think anyone can comment since it's not even out yet though in theory is that with the new Intel Processor, it no longer need a fan.
Won't say it's not possible because Apple engineers need to run an extensive amount of test to make sure this product don't fail quickly(last for 3 years at least). What sucks if this falls under 1 of those products that work up to 1 year and fails between 2nd and 5th year. All those without APP will start cursing because of that because Apple refused to launch a recall program.
A good example is the 15" MacBook Pro 2011 model which have a big flaw with the dedicated GFX. I'm affected by this myself and it even happened right after 3 years since I bought it. Fortunately I was able to get an exception for a logic board replacement and has been using it ever since. Scary thing is a logic board replacement is just a temporary solution, anytime later it's going to fail again because there's a flaw with the design causing the GFX card to get heated extensively over time
With that said, buying an existing line of product is not really a bad idea if you've done enough research about the product because NO ONE can guarantee you that the new upcoming model of Mac is the best and will last as long as you thought it should be.
