Well, I am a gadgetoholic-in-recovery. Let's skip lightly past the colo server running Debian that I keep the blog on. I'm mostly a Mac shop. On my desk right now is an older 23" Apple Cinema display, being driven by an October 2010 13" Macbook Air (4Gb/250Gb SSD, OS: 10.7.2). Next to me is an iPad 2/64Gb and a 3 mifi, with a ZaggMate cover/keyboard. And there's an iPhone 4 that ain't going to be upgraded until it's…
Wow. This is much more what I'd expect from a scifi writer, or really anyone who uses a computer all day professionally. Have you considered Microsoft Office 2011 for office documents? I agree about the ribbon, but it is better than the free alternatives. Why not upgrade to the 27" or a dell u3011 now, and mba11 later? Also, backups?
The 27" ... well, I upgraded my wife's side of the office to one earlier this year (pre-Thunderbolt) and there's a limit to the depth of my pockets. Besides which, my desk is already dwarfed by the 23" panel (and said desk is an obscure 1970's Swedish designer item, not something I'm likely to replace in a hurry).
Backups: Time Capsule for on-site, 1Tb pocket hard disk for on the road, and Dropbox as a sync solution and if-all-else-burns-to-the-ground fallback.
