OK, I sent you a few - hope one of them works… if not, let me know and I’ll check in a few other directories or maybe scan another…
I guess this is a little late but since I work at home when not visiting clients I’d thought I’d through in my $0.02 anyway.
Working at home does not mean you have to be at home. With a laptop, wireless networking card (cellular type), cellphone, and caller serveices like call forwarding you can set up your office almost anywhere.
I personally use call forwarding to dirvert my calls to my cell phone. Also I can use my 2nd cell phone to connect to the internet and to fax out (and in if set up in advance). For incomming faxes I use efax.com which delivers my faxes via email .tif attachment. Efax can be used to also send faxes buy I rarely use that function but nice to have because I needed it a few times.
I use my mobile office to be ‘in’ my office more often then I am. Also I am buying a vacation house and plan to be able to run things up there as well as here.
As for the size of your office 9x12 is OK. Go with an L shapped desk and put in so you face the door. I put cabinets almost anywhere where I had space (el cheapo plain white home depot cabinets). This way I can hide clutter and it does make it easier to find stuff.
Gooooood ideas. I do have an L shaped desk, but I face the wall0 which has two windows that allow me to look up into the sky and trees !
I can’t run my office by wireless units. I have to sit here…and watch video images on the TiBook, and learn to edit them together to tell a story.
Still there are some dandy ideas here, thank you all so much !!! When I trick it out, I’ll find a way to link in a photograph.

Consider yourself lucky. I have a bedroom/office/art studio crammed in a space about that size, and NO window or view at all. And my chair is under an air-conditioning vent that causes me to wear a sweater year-round. The width of the room is the length of a very small twin bed. I also have a desk, hutch, dresser, bookshelf, easel, and a huge stack of frames piled behind my desk chair. A folding metal card table chair. I’m too cheap to buy anything nicer and this is what I got when I moved back. The computer monitor and printer take up all the desk (which has a very small surface area), so I use a wooden TV tray set to the side of my chair when I draw and paint. Every inch of wallspace has something crammed on it too. Wrapped pictures are piled on top of the dresser, boxes of reciepts, papers, frames and a small handful of books are crammed on every shelf.
But hey, I get to live here for free, and I got my cable modem (business expense!), so I’m not complaining.
I think your office could use an original painting on the wall. 
But really, you want to make sure you enjoy your surroundings. I’m the burrowing type that likes being buried in stuff in a small enclosed area, and I think a window would be kind of distracting.
I’m a southerner, but I’ve been up north quite a bit, and I think basements are very cool. There’s something comforting to me about being down inside the ground. I’m also a “people person,” at least in that I like to talk, but I remedy that with a full-time job in addition to the ~ 20+ hours a week I spend working in my “office.” 
I guess I’m also the burrowing type, and so prefer to face the walls ( and windows ) than out into a dark dreary room. To me, the room is the problem and the windows are the saving grace. It probably flies in the face of Feng Shui but there you have it.
I can watch the squirrels do battle, mark my time in here by the leaves that fill my field of vision for half of every year, see the snow flakes stick to branches in bitter winter. If I had my choice and the money to do so, I’d make this corner of the house all glass. Of course, structurally that might be an “unsound” idea, but heck…
jinwicked has focused in very well on what appears to be the real source of concern with me, with this home office. It’s not just about being a people person or not. I doubt very much whether or not this space will give me much creative satisfaction. I’m perhaps judging too early here, but the video editing depends on the craft and eye of a production team, a cameraperson, etc. I know intellectually that a good editor makes footage into a moving powerful story, but the truth is that I don’t see the art in it now. I see only the technology. I can master that eventually.
Luckily I have the sculpting and photography to keep the truly creative juices flowing. I just dread seeing this as a prison cell instead of a good small office…
