Well, there is no choice other than wipe it, since LinuxMCE doesn't let you partition and set up dual/triple boot.
If it would let the user partition like he wants (for dual or triple boot, OSx86 and Vista in addition to LinuxMCE for example), I would leave it.
There is also other stuff, like games and video editing that don't work on Linux, and Wine and VMware is no option...
OK, there are some cool games like Sauerbraten, Frets on Fire, Stepmania for Linux (btw. which could be included in LinuxMCE by default), but most popular online games are Windows only.
Add to the feature list:
- let users do the partitioning
- or even better, create a DEB package, so users just apt-get it into an existing kubuntu installation
