Here's one for you computer geeks out there...

Get a travel router. Allows you to plug in the room's high-speed CatV internet cable into a very portable (as in almost cigarette-box size), wireless router, then use it as a wireless hub in your hotel room.

That way, with the exception of the mile-long cable in NRT, you're not tied to the desk with a 2' cable when you're trying to watch your slingbox, checking/writing email, writing a book-length reply to APC forums, or *whatever*.

Multiple choices out there. Some under $100. Google "travel router". I've had mine for 2 years now...and trust me...it's much more comfortable reading your email relaxing on the bed, than a stiff-backed chair...especially in SIN where the desk is 30' away from everything. The brand I bought has performed outstandingly...I've never had problem with it...but it's only as good as the hotel's internet signal.

Okay, I'm a geek, but I know there are more of us out there...

P.S.--Make sure you activate the router's internal security features. And, like the current laptop power sources, most can plug into 220V+ outlets...but I'd double check!
