Uh, a Hp Jorana would be completely the opposite of futuristic and more or less like you're from the past.
Stick an iphone on your arm, that'd show everyone how futuristic you are.
You could do a period cyberpunk, e.g. 90's. Get some RJ 11 (Phone line/POTS), 56k external modems and drag around a crt monitor. It''d be hip, cool and no one else I know has done it before.
