As a former user from Native Oberon and BlueBottle OS back in the 
late 90's, I can attest that the GC was fast enough for powering 
a single user desktop operating system.

Surely there are cases where it is an issue, mainly due to 
hardware constraints.

While I am a GC supporter, I wouldn't like to fly in an airplane 
with a GC system, but a few missile radar systems are controled 
with GC based systems (Ground Master 400). So who knows?!
