I'll admit that I was hoping for the white roundels and a traditional console. Given that the TARDIS did a reboot, I don't know why it had to be so primitive looking. But then something hit me about it.
Having all the analog devices controlling this marvel had a neat feel to it. Kinda like a retro style, like someone that hooks a C-64 up to act as a serial terminal on a high-end Sun box - just because they could.
The other thing that I liked about it was they didn't try to be all futuristic. Look at the Star Trek ToS, or TNG. Look at the older console rooms, especially in the late Tom Baker era. All of those tried to predict the future and to add touches that had that far out feel to it. And now that we have moved forward a bit, it all looks so silly and dated.
By having a typewriter, you at least start out dated and it help it stand up in the future, plus it has the kinda eccentric feel that the wooden console room of the Baker era had as well. Reducing some of the clutter would be nice however.
I just hope we get to see more of the interior (and it doesn't look like backlot stairwells!)
