Re: buying a laptop
well the biggest thing about using u.s tech items in asia is that they have different power standards, in which case you'll have a blast trying to find an AC adaptor strong/light enough to carry around.
In that respect buy from Thailand, UNLESS you're only going to live there for a short while.
If you're only going there for a couple of months, then buy from here (generaly more choices) and buy a AC power adaptor that will allow your notebook to charge up in Thailand.
(i know this because i spent three months last year in pakistan trying to get my ps2 to switch on....not fun shopping for a huge converter either)
