I have 2009, 2010, 2011 and 2012 versions still operational in different locations, one running 24/7 as htpc. The latter only gets shut down by electrical power failures, common in S.E. Asia. I have had the 2011 ssd hard drive fried, by a lightning strike induced surge, and easily replaced by a 3rd party in Hong Kong. No other problems in 7 years.
