Sounds like it's time for a new computer for you. Im running a Gateway G6-400 PII 400Mhz 320Mb SD-RAM(Originally came with 64Mb) with an old 3dfx Voo Doo card(I think the first one). While the computer runs fine watching dvds can be a annoying experience. Also while simultaneously running DreamWeaver and Fireworks i ran out of memory. How do i run out of memory when i have 320mb of it? How much memory do i need? I suspect it is windows 98 falling to do its job since every time i close my windows media player the OS fails to deallocate it from memory and i have to ctrl-alt-delete to get rid of it. I would like to wait till some advancments are made before shelling out a couple of grand on a new computer. The 17 inch G4 Power Book is sweet though. I thought the following was really a nice touch......

Futuristic backlit keyboard with ambient light sensor
Another first from Apple featured on the new 17-inch PowerBook G4: a unique fiber optic backlit keyboard with laser-etched keys that’s right out of the future. A light sensor automatically adjusts the keyboard and screen brightness based on the available ambient light. In low light, for example, the PowerBook G4 automatically lowers its display backlight and turns on the backlit keyboard. Then light-emitting fiber optic strands located under the keyboard come to life and illuminate the backlit keyboard so you can continue to work, unaffected by the change in ambient light.
