The port on the bottom is really the least offensive element of the design. I know people find it fun to clown on, but if any of them had ever used one for 5 minutes they would realize it's a terrible mouse for a bunch of other more important reasons (weight, feet quality, tracking accuracy, polling rate etc.).
Yeah I hate that people go for the easy fodder, which barely effects real world use, and ignore the multiple actual issues with it that would make it quite poor even if the charging port was fixed.
