I'd like to unironically place this popup on public office laptops in order for users to collect themselves and stop being afraid of touchpads and keyboard commands.
Honestly with the tech where it is today, there's really no downsides to wireless with a dongle except maybe price at certain brackets. Most modern wireless gaming mice are as good if not better than their wired counterparts. If you don't care about sensor performance or polling rate, you can still get a cheapo wireless mouse that performs about as well as the cheapo wired mouse you were gonna get anyway with the added convenience of no cables.
If you use this laptop on the day to day basis - yep. But if a notebook is brought to you for a limited time to open one single presentation and show it on the screen\projector with a clicker I don't really want to bother with carrying a mouse too. It's needed for three clicks total.
