Linux is effectively one- what changes are the included packages and the administration tools.
Adding a couple of fstab entries to mount your Windows partitions is not so difficult, although all three distros can do that under their administration tools too- so no need for console. They can even mount NTFS partitions as read/write (current kernel versions allow this luxury), but this is not advisable.
Personally I use Mandrake 9.1, which had many applications broken when released (no surprise, the same happened with version 9.0). Applying the up-to-date fixes "most" things work OK. Red Hat has virtually cut the knot with KDE, which is not really to my likings, and SuSE is great, but commercial, which is also not to my likings...
The revolution cannot be a lever, or an essay, or tablaeu, or embroidery. It cannot proceed mellowly, piece-by-piece, gently, devoutly, simply and humbly.
