One of the most interesting tidbits comes from Walt Mossberg of The
Wall Street Journal, who reports that the $29 Snow Leopard upgrade
advertised by Apple as being only for current Leopard users will in
fact install on systems currently running Tiger. Apple's official
policy is that Tiger users are required to purchase the Mac Box Set,
which includes iLife '09 and iWork '09 in addition to Snow Leopard,
for $169.
