I'm currently running a Surface RT in my 2002 Maxima. I have the base of the mount in the dash but I'm still working on the trim bezel. If and when I ever finish that part of it, I'll be sure to post pics. The RT version is MUCH easier to mount but very limited due to the lack of apps. Easier to mount due to the fact that the charging port and usb port are on the same end. So when I slide my RT into the mount, the charging port and usb ports are fixed at the bottom allowing connectivity to power and to the 7 port powered usb hub mounted behind it in the dash. Beyond the hub I am running 1 non-powered 4 port usb hub (basically for low current usb thumb drives), 3 laptop hard drives (salvaged from past carpc's) and a usb audio adapter to get my optical signal to the Audison Bit-One. So far the only major problem I've run into is that the cheap cases I bought for the hard drives. One of the drives seems to always work. But the other 2 are completely random. Some days they all power up beautifully, others, I may have to remove them and slide them back into their respective dock.
I'm looking into the SP2 as an upgrade. But I'm still working out the kinks of docking it in portrait mode as the usb and charging connections are at opposite ends. Considering it took me 4 tries to get the power connector to line up perfectly with every mount on the RT, I'm really not looking forward to rebuilding another dock. But then again, I think it's the build that I enjoy the most. Otherwise... why would I keep changing everything? LOL
As soon as I make the decision about the SP2 vs my RT, I'll finish it off and get some build pics up.
