we get IT expos over here with stuff on sale, then right at the end they'd sell their display units for super cheap.
Got my i7 Samsung lappy for RM2,200 (roughly 400 quid) about 2 years ago in one of those. Even dumped me a rubbish printer for my troubles. The lappy is decent, not the best, but runs most games I've wanted to play on it and runs the heavier software with no problems.
