Thinnest laptop in the world

I just bought an overpriced, underpowered laptop with a foot in the 'stupid netbook' mass grave. But I like it.

 489.9g

I looked out for international warranty first - Sony, HP, Fujitsu, Apple (doesn't make laptops) etc. seemed good with their web of coverage.

Then the next thing on my head was, "I need something that will fit easily onto lecture theatre desks," followed by, "It has to be easy to carry around."

Lastly, it was, "Will I be able to write in Python on this?" Duh. "Put in a full LaTeX package?" OK... "Put in MATLAB and Mathematica?" Okay... "Still have space for W7?" All right... "Still have enough space to save my files?"

I'm sold. Oh by the way, it weighs 640.2g in full lol... I removed the battery so that it won't overload the scale. I'll take a look at how to tune it further ^^
