U3, Meet Your Competition

Meet MojoPac: it's a $50.00 piece of software that basically does what the U3 software does…only in some ways it seems, well, better. Like you can install it onto any USB drive (flash drive, iPod, portable hard drive), add any programs you want (no need to purchase the micro-sized U3 versions) and run them from the MojoPac shell program – no installations, no footprint on the host PC and you can switch back and forth between MojoPac and the host PC without any problems. If you've got a lot of programs you want to run and need a bigger sized drive than U3 can provide, MojoPac might be worth a look.
