If it is coming preinstalled, then I would use it. Then once you get more acquainted with Linux (or if you already are), installing a
real distro would be the way to go. A suggestion on another distro would be
Ubuntu (as mentioned before) or
Slackware (only if you want to go to the simple, yet advanced side of Linux).
Linspire may have the presence of windows while being Linux, it still is a good way to start out with Linux without having to install and configure.
