It's the only way I open the start menu. There is no faster way to get to what I want than Superkey and typing.
PS I have all my OSes set up similarly. OSx has spotlight, my GNOME and KDE are configured to launch searchable menus on Super, and my mobile launcher is set up to search when I swipe up.
A microwave works by bouncing microwaves around the interior. Since the shape of the container doesn't change neither will the path that the bounced waves take. This can lead to hotspots in what you're reheating.
To mitigate this you have a few options:
Both approaches redistribute the hotspots to maximize even heating. The efficacy of either approach will come down to the specific design of either unit, but a tray-less unit can be easier to clean, and with fewer moving parts exposed to end users can be a good option for commercial/high user count settings.
Each design accomplishes the same task of relatively even heating with few hotspots.
