Assuming your plane lands on time (unlikely) and you deplane in 10 minutes (also unlikely), the website linked above shows the transit between 2G and 2E to be 30-40 minutes with the passport control. Let’s say you catch the shuttle immediately so take 30 to be optimistic (also not likely)

So with everything going perfectly, you will arrive at your departure gate at 09:00, a half hour before departure and probably after boarding has already started

More likely is that your plane will be late landing, some guy will struggle getting his bags out of the overhead, you will just miss your shuttle, the person in front of you in line at passport control will not be able to find their proper documents and you will arrive at the departure gate to see your flight pulling away from the bridge.

Even developers, who are among the most tech savvy users

Doubt

I have owned 3 G203 mice (never again) and they have all failed the same way, with the left mouse button switch failing and causing double clicks/inability to select anything without resetting.

Quality must depend on which model you get.
