I've only flown VFR but I can imagine that especially for IFR flying you need to think seriously about where you're going to locate all your stuff to have it to hand, and visible, even if you need two hands to fly the plane.
I too thought that not being able to use an A4 clipboard and not having a yoke clip would be a problem. But no...I use an A5 clipboard strapped to my leg which is fine for holding approach plates, A5 plogs, pen, paper, timer, whatever...Not that you need all that rubbish
Load the approach into the G1000, reference the approach plate, start the timer soft key and you're all set .....
