Okay, I might be completely dense and missing the point of this thread, but I am absolutely baffled at the hardware discussion regarding WRITING TEXT on a computer. I mean, hasn't Stephen King written REAMS and REAMS of prose on his Batman-esque Pismo G3?
I've done audio production and video production work, and for those applications (especially video), heavy iron is necessary for getting things done. Dual monitors are a must. So are gobs of RAM, fast CPUs, and rock-solid, stable and rocket-fast i/o. But writing? Word processing? Didn't we cross that threshold with the Timex Sinclair?
Software is perhaps a different story. I've used FinalDraft in the past, which is okay, but the customer service is draconian. I'd gladly switch to something else, and the Scrivener buzz has me wanting to have a look at the demo. Right now I am writing a piece of historical fiction, and I'm just using Pages, which seems to be handling the scale of it reasonably well (98,000 words/315 pp. at the halfway point). I have to finish this draft and do at least one complete rewrite and copyediting run before I need to worry about coding for Kindle/iPad/Nook e-readers. It might have been nice to have used a software aid for structuring my book, but it's really an adaptation of an earlier story from another project, so I know where its going ahead of time. Still, I'm going to give Scrivener a once-over in case it can make my life a lot easier.
I suppose if a person were were doing a large research project and wanted a lot of windows open for reference material, research findings, etc., maybe a dual monitor would be helpful. But I wouldn't think dual monitors woul be as necessary as they are for graphic designers who need a dozen palettes open; or audio engineers with sample libraries, track samples, and mixers to view and tweak; or video editors who have audio and video plug-ins and multiple video streams to pull from.
I've run dual monitors while writing, but only to have a free window to surf from when I need a small break. I certainly wouldn't NEED a second monitor to get things done.
So help me understand the hand-wringing over what hardware to use for writing, because to me it sounds a lot like a serious discussion regarding what kind of crane you'd need to lift a feather with.
