I've have had it for 2 days, and so far it's soloid as a rock. Bryce and Blender 3D had no problem with its .obj at all. I even used it while rendering a heavey Bryce scene, it did slow down but that was it. I run XP Home fully fix packed, on my AMD Athlon XP 2600+ with 512 MB of RAM. I know I've only been using it for a short time, but usually you know within a day how stable things are. Mark...;)
