Memory Hungry

I'm thinking of buying JackFlash for my Sony NX60. This amazing piece of software costs about $20 and will give extra 4800Kb of space (ROM memory for application usage) on the NX60. It does this by making the "Read-Only memory" of the handheld writable.
The new version of Docs To Go really slow loading documents with some of its programs (notably the 718Kb size WordView+) on the Memory Stick. I realized this because on the Tungsten E which has a much slower processor than the Sony NX60, but oodles more memory, the same version of Docs To Go loads documents really fast.
