[Qgis-user] What hardware for QGIS

Hi,
Thanks for the replies, very helpful.
Looks like I will be going for Ubuntu VMs for Q-GIS, but a full
seperate windows boot for Arc and Manifold.
I assume I can reference any drive on the machine from Ubunto
regardless of whether it is in a Windows file system or the Mac file
system (i.e. so I can do part of the work such as output cartography in
Arc/Manifold)?
Thanks again,
Neil
