With an 8Gb USB drive, mobile computer repair gets very easy.  Not only can you store entire anti-virus/spyware programs, plus updated definitions, with newer motherboards you could set it up as a boot device for MemTest86 and other boot programs.  Virtual-Hideout has posted their review of the Corsair 8GB Flash Voyager.

"I can totally recommend this unit to anyone looking for a large capacity USB 2.0 flash drive. You just can't

beat the warranty, the durability and the read/write speeds of the Corsair 8GB Flash Voyager."
