I ended up picking up two 32GB Corsair Flash Voyager GT USB 3.0 for $35AR each, can't wait to test them out. I was pleasantly surprised at how fast Windows installed from a USB 2.0 drive on my current USB 3.0 compatible system, so I'm eager to see what it's like with a USB 3.0 drive.
Also eager to try out a multi-boot USB since I will have the space. I'd like to put Win7, Win8 Developer Preview, and Ubuntu 11.10 😀
Also, someone on the forum put an idea in my head about setting up Windows inside a virtual machine inside Linux, to have bootable portable Windows. Pretty neat idea. 😀
