My 2007 top of the line MacBook Pro 17" lasted 7 years. Now this is even taking it to work every single day during those years, dropping it once, and fogging up the machine to the point where it stopped working, which happened twice (those deadly hot, humid, rainy summer nights in NYC). Damn, this computer was a trooper!
Two batteries bulged out and were replaced for free, the NVDIA graphics card croaked after three years and was replaced free no questions asked, and I upgraded the hard drive myself three times (original 160GB---->320GB---->500GB---->700GB hybrid).
Actually, the laptop still works (running Snow Leopard), but it will only do one thing: play movies from a DVD. And the CD/DVDS drive was never replaced or even serviced! Go figure.
A few months ago I bought a top of the line iMac, will be buying an iPhone 6+ before Christmas, hope to get an iPad Air 2 when they are released, and hope to replace my 2010 MacBook Air with a new Air, small MBP Retina, or one of those rumored 12" laptops.
