I wonder if technology from Better Place (http://en.wikipedia.org/wiki/Better_Place) was in any way an inspiration? They had developed a battery swapping system in 2007.
Actually, it's the other way around. Shai Agassi (founder of Better Place) visited Tesla several years back, then went on to found Better Place after what he saw:
Wasn't there a preorder that had the new ones (32bit) for 5$? Wish I'd have gotten in on that thing. Maybe that's causing a little confusion on the pricing here.
Edit:When talking about TI, i thought I'd share this subsite by TI (http://tideals.com/) for anyone who isn't savy on it yet. They don't have a deal right now though.
I second getting the TI Launchpad. Great and super-cheap piece of kit
With Energia (http://energia.nu/) you can even use your Arduino sketches and run them on MSP430 Launchpad!
