Well, whatever the underlying reason, Windows handles it far better than 
Linux. That's the perspective of an end user who just wants to get their 
work done.

I can plug my girlfriend's Android phone into my Fedora PC and Nautilus 
will hang whilst trying to display her folder of photos.

I can plug the same phone into Windows 7 (running on less powerful 
hardware) and it is perfectly snappy.

Therefore, with my developer hat on, I assume that the underlying 
subsystems and APIs on Windows have been far better implemented than the 
GTK/ATK accessibility stack on Linux.

That is not a criticism of anyone - particularly those on this list - it 
is just a fact of life.

Perhaps by comparing Linux and Windows more often we can identify the 
things that Linux is pretty poor at, and eventually try and put them right.

However you look at it, the accessibility stack on Linux has some pretty 
serious performance issues when dealing with large quantities of objects.
