More on Katmai install
Reporting Services offers a "set it and forget it" option in the install, to pre-configure using default values instead of making you do it manually....don't recall if this is available in 2005. Also offers a Sharepoint specific config. This could save a lot of frustration for the small business user.
By default, the "report stuff back to the mothership" options are both selected (error reports and feature usage). Hopefully, this is just for the CTP and will be unselected by default in the RTM version.
