@Daidalos: Been running P7 in Ubuntu (from 7.04 to 9.04 64-bit and all the versions between) happily for over 2 years. The success of running it seems to be related mostly to graphics drivers. My good personal experiences are with nVidia cards and quite many users with issues are apparently using ATI cards or some integrated low quality chips (like is the case usually with laptops). Getting Poser to run is not hard - mostly just installing the proper stuff - but running Photoshop would be a totally different matter. If you have CS2 or newer ... it's very possible you will not get it even to install. There are several very complicated issues surrounding Photoshop CS versions under Wine, but earlier versions apparently run well or so I've read from various Linux forums over the years.

Linux's command tools open up wondrous options to Runtime maintenance that are literally impossibe in Windows without specifically written applications for those tasks.
