I just did an install of Solaris 10u6 yesterday and it was dead simple. During the installation, the installer asks you what software group you want to install. Select the "Core" software group or the "minimal networking" software group. I agree the documentation is confusing. That is because (1) Sun documents everything so there is a lot of it to weed through, (2) most installs of Solaris are done over networks using install scripts to ensure every installation is identical, (3) Solaris can do things like install a new OS on a remote system that doesn't have any OS on it, and the documentation for those things drowns out the smaller, simpler documentation for the simpler installation methods.
