I'm not sure the firms you mentioned have the numbers you look after and
if they publish such numbers they are correct and how were calculated.
In general AS/400 is known as the most reliable machine.
We work with AS/400 from its debut and before we used S/38.
Now we are a the largest AS/400 shop in Israel and our experiance is the
mean down time of any of our AS/400 is no more than 1 - 2 days per year
and part of the failures are caused by a human mistake.
If reliability and availability are very important for your org. the
only machine you have to consider is AS/400.
There are also othe qualities you have to consider like AS/400 is one of
the most friendly computers or the strng security system of OS/400, etc.
