The single user version of Snow Leopard, ($29), is top of the charts with the second place taken by the five-user family version ($49). Both prices are aggressive when you consider the OS has traditionally cost in the region of $129 for each release.
Apple is also selling a Box Set (Snow Leopard including iWork and iLife):$169
for $169 or $229 for five users. The server edition of Snow Leopard, called Mac OS X Server version 10.6, costs $499.
Some key caveats: the OS will only be available for Intel-based Macs as it requires this hardware because it’s the first Apple OS to be truly 64-bit. Mac users still on a PowerPC Mac may be motivated to purchase an Intel Mac, though, as Snow Leopard promises hugely significant performance gains.
The OS is expected to ship next month.
