Hey Guys With the iMac moving to a 5k resolution, I am still holding off purchasing a new computer given there is no ultra hd content on the iTunes store to take advantage of the new display. When do you think we will start seeing Ultra HD movies and tv shows emerging on the iTunes store? Another question i would like ask is, should i hold onto my 2013 iMac in the future?, as I have this fear that when the new ultra hd content emerges they will change the file format and introduce newer software which will render the existing SD and HD content obsolete. That said do you think Apple will ditch a widely adopted file format, or will the existing content still work for many years to come. I would like to hear your thoughts on the matter, as I have invested a ton of money, since i upgraded my late 2009 machine for a 2013 iMac, which as you know ditched the physical media drive and got me hooked into purchasing my movies from iTunes.
