Things have changed a little over the last decade or so.

Back in 1999, we had Sumatra/XSI 1.0 running on a Toshiba Tecra 730 CDT laptop (Pentium 150mhz, SVGA Color 12″ display, 144MB RAM, 3.7kg).

Fast forward to 2011, and we have Softimage running on an 11″ Macbook Air (1.4Ghz Intel Core 2 Duo, 11.6″ 1366 by 768 display, 4GB RAM, 1.07kg).
Update: On the Macbook Air, Softimage is running under bootcamped Windows 7.
