I've used many different editing software and computer configurations... Non-Linear and Linear timelines, simple cut/join applications, notepad, small screens, large screens, single monitor, dual monitors, desktops, laptops and from starting with a 486mhz CPU up to my current dual quad core 2.93ghz setup. I've used tape decks as well as a single 20gb hard drive for the OS, Applications, and source to edit with as well as multiple terabytes of storage at my disposal. I've used slow USB 1.0 external hard drives as well as fast internal SATA III SSDs. I've spent over 2 years editing a single video and as little as two hours from beginning to end during live editing competitions. I've made things that were both meaningless and very personal. I've won awards and received praise. I've also accepted harsh criticism, both artistically and personally.
If there is one thing I couldn't live without it would be not being able to physically and mentally express myself on the timeline. Everything else is just a tool or a product of that.
