We introduced you to MobaLiveCD around this time last year—then, it only supported LiveCD disc images. Now you can use both LiveCD ISO files and bootable USB devices. In our tests we were able to boot a variety of Live USB installations like Ubuntu, GParted, and BackTrack.
Using MobaLiveCD is significantly slower than actually booting into the LiveCD/USB and notably slower than running the same LiveCD/USB in a virtual machine. Nonetheless, it's free, an absolute breeze to use, and it allows you to rapidly check out a Linux distribution with very minimal hassle.
MobaLiveCD is freeware, Windows only.
