OMG I owned a crappy computer my entire life. I would buy a good one, and keep it as long as I could (10 years)  it would run like crap and I would grin and bear it.  WHY.  I bought this as a SECONDARY. it runs better than the new one I bought(!!!!!!!!)  its called a refurb.  its not used. it probably had a software issue that some tech had to fix.  its the best running computer I ever had.  and I've been in the game since apple IIE.  GODS HONEST TRUTH: best bang for your buck.
