Apple seems to be making better and better iMacs.  This one is a beauty - fast, amazing display, powerful, newest operating system easy to learn.  I don't quite know why the review asks you to review thickness - for years these iMacs have been thin.  And sheerness?  One thing I do like about this new model is that the unit high enough so that when tilted forward I could. slip a sound bar under it.  The 5K Retina display is almost scary!  There are a few features of the latest OS that I find cumbersome and many that I have no need for.  But there is nothing else for home use that compares with this unit.  One complaint: All the cardboard and styrofoam involved in shipping this is a nightmare to get rid of.  Some of the cardboard is so stiff it is difficult to handle.
