My late-2007 24" iMac is on the fritz and in need of replacement. It has gotten to the point where I can barely do anything besides basic internet browsing and listening to music. I like to use Adobe Creative Suite for graphic design and photo editing as a hobby (in addition to some video editing) but have been unable for a while because the computer lags. I know there is always something newer and hardware bought today is dated pretty quickly. I can deal with that. What I would kick myself over would be if some critical hardware was added to the next iMac that wouldn't allow me to use the next wave of new products. I'm thinking hardware that would allow for things like... wireless charging (iWatch), Thunderbolt 2, etc. I know nobody knows for certain but, any thoughts? I have a refurb 27" late-2013 iMac ready for me to pickup in-store but this concern keeps eating at me. Please help reassure me this thing won't have hardware limitations in the next 2 years.
