With too few OS/2 magazines, we don't mind the journalism, Lewis. The
problem for us and "b" is mostly that the prism-based "b" cards with
drivers are going away. (In the US) Netgear is no longer listing
theirs. (And, they came with 5 yr warrantees. Will I better off should
mine fail before Xmas '05 at age 3 and they send me a current "g" card
for which there's no driver?
Otherwise, I wouldn't care.
