You can still use tables and CSS display:table (you should use the latter if the content is not actually tabular data so as not to make life annoying for people using screen readers).

But for those of us building sites with complex layouts (and situations where we can't be entirely sure of the contents, e.g. using a CMS or static site generator), it's really amazing to finally have tools in CSS to actually do page layout.

Oh, I very much agree... but I recently took the time to come up with a nice layout using flexbox (really my first time delving in without relying on a framework for most of it), and it wasn't too bad, some of the naming conventions are weird. But then I pull it up in IE11 in a VM and Safari... man, those were painful to fix. Yeah, I was maybe missing things, or the defaults aren't as sane as they could have been.. but Chrome and FF looked/worked great, but Safari in particular I had to redo things... then back and forth until it finally worked across the board.
