I agree. I think that some issues will naturally evolve away, like resource
issues. That is always a big thing with new technologies. When OS/2 was
released, there just weren't enough machines around with 2 or 4 megs of ram
for it to be realistic. Now, OS/2 would be by far the slimmer OS and with
greater stability and functionality.

Sure, AS/400 people will not develop on technology that they don't trust.
That is part of the nature of our shops. But you realize that NT shops were
developing "mission critical" applications when NT was still running less
than 95% up time? AS/400 shops saw that as insanity. Personally, I
understand developing the apps, it was rolling them out that was insane. But
customers actually deployed these applications and kept them! I was involved
(against my will!) in a rollout of an NT credit reporting app that had very
poor reliability. The shop was an otherwise solid blue big company. But the
MIS people who deployed it liked the ability to show off the GUI to the
boardroom. The whole rest of the company, including all the data collection
for that app, ran on 400s. That app was only approved on NT because it
wouldn't kill anyone if it was down for a while. But that was the flashy,
showy app. I really could have puked.

I just wish an AS/400 software company had simply built a GUI front end to
all that 400 data.

The beauty of developing servlets, jsps, Java applications and applets, is
we really don't have to trust IBM to keep its commitment. Don't get me
wrong, I have had a lot of success with IBM, but I suspect they are in
business for them and not for me. But if IBM doesn't roll out the dependable
backbone for what we want to do, someone else will. I truely want to make
sure that AS/400s are always there as my server of choice, but I owe it to
myself and my customers and employers to not rely on that.
