How intrusive/problematic is the Solidshield DRM used by EA?
The DRM limits the game to 5 lifetime different machine installs (e.g. install on up to 5 different machines simultaneously. Uninstall one of these, and you should be able to reinstall on yet another machine). Note that you can effectively "lose" one of these installs by losing a hard drive, re-imaging, etc. without uninstalling first.
