Is your productivity linked to your tools?

I used to think, and still, kinda do, that my laptop was the ultimate in productivity. The only thing I couldn't do was work whilst at the school, waiting for the kids.
That was, until I started university. And the laptop died. And the DESKTOP exploded. No joke, my desktop went *BANG* about a month ago. So we bought a new, vista installed desktop. And at the same time, I went for my disability assessment, cause the University referred me (my university ROCKS!), and eventually discovered I was getting a whole RAFT of tools that will tighten up my study skills.
So it all arrived this morning.

I didn't open my laptop first - I opened my dictaphone.
Y'see, I'm firmly of the belief that if something is working for you, augment it. I work well as a multi tasker. I can write and talk at the same time - I don't THINK I can write one story, and dictate another story, but I think I can write, pause when something else occurs to me and then go back to writing what I was working on.
Whether this rather wacky plan increases my productivity, or leaves me with more ideas than I know what to do with, which actually, is an improvement on coming up with snippets then losing them in the avalanche of the rest of the day, or whether I just run round in circles.
I am curious however, have you done anything recently to increase your productivity? Has changing the machine you work on increased your productivity, or has it left you the same, or worse off?
