Folks,
Just for information, Omni, who produce a couple of well-regarded OS X
applications, have published the OS versions reported when their
applications phone home for updates <http://update.omnigroup.com/>
(the 'Major Version' display is the most useful).
Right now, 10.6 is 25% and rising rapidly, 10.5 is 40% and falling,
and 10.4 is 35% and largely static. That is, it appears that the
majority of the 10.5 users are converting to 10.6.
The various 'Minor Versions' graphs -- in particular the 10.5 graph
-- suggest that people install updates (including Java updates, I
presume) essentially automatically: there's a two-week time constant
which more-or-less matches the two-week interval between (system)
Software Update polls. This matches my perception of how folk do this
upgrade.
<http://adium.im/sparkle/?year=2009&week=39&graph=bar#osVersion> shows
some different statistics -- Adium is a Jabber client. That also has
10.6 at 25% at present.
See you,
Norman
