I haven't checked Linspire. So don't know much about it. You can check it out at
http://www.linspire.com/. I have never used Linspire so don't know much about it.
But it is better if you don't install a Live distro on hard disk. Afterall live distros are limited distros due to space constraints.
Yuo can try out Mandrake 10.1 (given on Digit DVD) or SuSE (given on Digit DVD) or Fedora Core (given on Digit DVD) or PCQ Linux 2005 (with me

). I use PCQLinux 2005 in one machine and Mandrake 10.1 in another.
