I'm a 16.04 user, too, and I've been running 18.04 in a VM for a few weeks. Basically seems ok to me, but, I do have some gripes. Not deal-breakers, just dislikes: * When copying a file in the gui, a progress window doesn't pop-up for the operation. Took me a little while to realize there is now a little icon on the window's titlebar that shows a pie-chart style of progress. Until I look for that icon, it feels like I don't know if the copy even started. * The "start menu?"/launcher thing blows up into a big, full-screen, icon menu. Seems mentally jarring to have all of my current work overlaid by the launcher. * And, my biggest gripe is the least consequential, but, I want my wobbly windows and 3D desktop cube back! There, I admitted it. I used them and liked it :)
