I've recently got back from a trip to Malaysia & Singapore, I met up with a colleague who moved there 6 months ago to start up an office due to us expanding our client base massively out in Asia and if I wasn't with my girlfriend and had the opportunity to work there for a bit I would definitely take it.
There is a large ex-pat community there and English is the official language so you won't feel massively overwhelmed by Asian culture if you're worried about that. It's incredibly clean, the metro is very efficient and a much nicer place to be than the Tube, you'll get used to the heat quite quickly - you just learn to not going strolling around at mid-day etc.
The only two downsides for me would be:
• The food - I really like Asian food, there is a great food culture there (not on a par with London but it seems to be really taking off) but you
will miss Western food, my colleague seems to find it quite difficult to find a decent sandwich for instance
• Cars. Just going by your signature this might also be a big issue for you. I spent my entire time there rubber necking as there is a ridiculous amount of beautiful cars (and girls

), especially modified JDM stuff...but you probably won't be able to afford one yourself. Cost of car ownership is incredibly high there, with a very complicated system that involves you paying thousands just for the ticket to be allowed to own a car, before you even get in to the huge tax laid on the purchase prices. Of course I don't know what your salary bracket would be - this may not be an issue at all.
Other than that I would quite happily live there for a year or two, maybe longer depending on how it went. Rent, food etc. works out to be about as expensive as London but you'll make massive savings on income tax so it's a financially sound move too.
