When Will C2D be obsolete?
Well listen icemantx, if you like your iMac and you feel that it does everything you want it too, then don't worry about these other guys telling you to sell your P>O>S. They are way out of line to even say something of that nature to anyone. Snobs, don't degrade a person's means and wealth. Im here to tell you that these C2D Macs actually run pretty good when upgraded to the latest OS X. For Example: I also have a 2009 iMac 2.4GHz 4GB Ram operating on 10.10 Yosemite. I downloaded the Beta key and gave it a test drive, guess what? It operates great. A much different look than accustom to, but nice. No pizza wheels as these guys are saying, great performance. So my thought to your question, I think that the C2D will actually be around for a while longer. Why I think this, There are many machines operating with C2D all the way up to 2010. That only puts these 1200 - 2000 dollar machines a few years old then losing support. Apple users will be very unhappy having to repurchase a computer they thought would last them at least 6 years of excellent use. That is why we buy Apple and not Windows. Better performance, virus non existence, life, programs, and many other reasons. So if my Macbook Pro Early 2008 and early 2009 iMac will support Yosemite, then we have no worries for at least another 2 years. But those are my thoughts. Oh and wait before upgrading to 10.10, it is based around IOS and not OS X. I think Apple is trying to make the turn to IOS and cut out OS X.
