Get yourself to Shinagawa station this week for an unusual intersection of computing and trains.
Google Japan is holding an event at the new Shinagawa shinkansen station until Friday. Go to the Virgin Cafe and take a quiz; if you get the correct answer, you'll win a Google prize. Everyone gets a Google keitai strap.
Now if only you could Google while on the shinkansen...then I'd pack my laptop for our holiday for sure.
Ummm, how about through the power lines :-p If they can do that at home they should be able to do it on the Shinkansen.
If France can do it...
