In case you didn't click the link, Michael doesn't make it clear that
he copied and pasted Carmack's actual comments, which are over one year
old. John also used NetBeans to develop, and criticized the IDE
performance. I use Eclipse, and see less slowdowns than I do in
VisualStudio Express. Java, .NET, same thing really, and MS is going
for the same markets (gaming etc).

Michael, you neglected to quote from John's recent post:
"O&E [game name] added a high end java version that kept most of the
quality of the high end BREW version on phones fast enough to support
it from carriers willing to allow the larger download. The download
size limits are probably the most significant restriction for gaming on
the high end phones."

This much more strongly implies that Matt is correct ...
