How about...
4) A PDA with wireless capability?
Some of the new PDAs (Dell Axim x51v, among others) offer wireless, VGA screens and Windows Mobile 2005. For the limited email and web browsing needs you have, carrying one of these would be far lighter than carrying a separate notebook computer - and it would be completely off your company's system, so no chance at all of being snooped on or compromising your company's security.
