Leaving Japan

Fast post!
I finally got my luggage, I have now clothes and stuff, so it is looking quite good for the next leg.
After breakfasting the best sushi on the planet, we are going back to see crazy Japanese girls in a park and then going back into the airport. AS you may imagine, I am really looking forward to going back to the airport, but I cannot avoid, because the next leg of our journey is coming this afternoon.
Anyway, I think it is worth writing two lines about the japanese. They have this amazing capability of making me feel incredibly clumsy and inelegant, not sophisticated and generally a lees evolved kind of human. But the most surprising thing is that I already had this feeling the first time I was here and even though I knew it'd come, I've fallen in again! Talk about seasoned explorer and intrepid adventurer...
Luckily, I do not expect a lot of elegance in our next country, mostly the contrary...
Just to give you a hint, we are going to fly even further away from all of you. Yes, we fly further away and the flight lasts 11 hours. Where can we fly to if we are already 11 hours away from home?
Yes, we are going there...

I firmly decided to buy no iPad, but instead a nice, nice laptop to fly back and forth from England and have my steam library on the plane. I will get it when I am back under the sea, but I would gladly take suggestions.
As a first set of requirements I need something with a graphics card, a reasonable processor, like a i3 or i5, nice amount of RAM (2Gb or more), 13" display maximum, as alight as possible and as much battery and HD as possible. Ideas?
