Yes. I tried Operas Aria and asked a bit about HP1000 A-series. I started by asking the difference between A900 and A400 and got a reply that was partly correct, then followed up with some specific questions about the A400 that I happen to know rather well. It insisted that it had only 32Mb and it corrected itself.
But the problem as always was that the answer LOOKED ok, but there was no way, without prior knowledge to weed out the errors. -- Med vänlig hälsning Anders Gustafsson, ingenjör
