Have the option to grab an LG Ultrafine 5K for $800. I googled it, just for means of doing research, and learned it’s unavailable for pickup at any Apple Store near me (there are several). I suppose my question is - is $800 a decent price and, more importantly, is it about to be replaced? If so... should I wait and see? I don’t know that monitors “lose support” (but maybe they do).
