yeah thats what i was thinking. Accually on the contrary to that, i find gimp to be superior to photoshop in both memory allocation and functionallity. As far as USB support goes, the new 2.6 kernels have amazing usb 2.0 plug and play support as well as usb printer/scanner support etc.
The apple OS 10 now runs on the linux 2.4 kernel, because of its advanced multitasking and memory allocation properties, something that windows lacks, and allows apple computers to be the prefered brand for multimedia editing.
