The iMac could be due for an update in the next couple of months ...
maybe, possibly, perhaps. Only Apple knows for sure.
Currently the 27" iMac (non-Pro) is the only one that has easily
user-upgradable RAM via the trapdoor in the back - it's pretty much the
ONLY easily user-upgradable Mac at all these days. If they re-fresh the
design, then that could go, although with Johhny Ive now thankfully
gone, the trapdoor could much-less-likely make a come back in the 21.5"
model.
