May I have a cookie?
They wouldn't need to be large. I think the benefits outweigh the risk in this case. Water is much more risky than dust, and that will find a way in regardless unless this thing is waterproofed and stupid expensive.
If the vents are on the sides and the controllers are locked in tight and sealed it wouldn't be a huge problem.
Thankyou both for your input. I had assumed previous Nintendo handhelds were water tight. This isn't my area of expertise at all but if people more familiar say it can be done that's good news.
