omg this is soo cool, i'm currently installing a simulation app i use for uni to my USB stick so i can do some work whilst at my girlfriends

will let you know how it goes, i must say its quite slow but its just like a virtual desktop that runs from your external device

This is equally as good from what I have been reading . I'll give this a try when I have more time . Have a look in the library section for some good precofigured stuff .
