...except that these computer systems which are failing and grounding the
carriers are actually the same ones they've been using for decades.  I
presume you're referring to the high profile ground stops for United,
Delta, and American in the last few years?  Running on SHARES, Deltamatic,
and SABRE respectively, as they (or in UA's case, Continental Airlines)
have been running basically forever, on the same TPF mainframes.  I
would argue this is an example which goes directly against your point --
for more robustness they should have moved to more modern systems, and
their reluctance to do so is causing major failures.

Curious.  I hit the power button on my sleeping android phone and I get a
login screen ready to go in about a half second.  Ditto for going back to
sleep.  This was the case on prior phones too, even when other operations
on them got sluggish to the point of irritation.

Hmm - again, WFM.  What phone and OS are you running?
