The recent launch of Sony's PSP 'Lite' at a lower price than the original has obviously done the trick in its home country, with Japanese data showing sales of over a quarter of a million in the first four days.

Figures for the new ¥19,800 (£85) version of the handheld compare well with the previous two-month period, which saw the same amount of the old model sold over a much longer period.

Cynics might point out that the simultaneous arrival of the hugely anticipated Final Fantasy VII for the PSP was surely a major factor, but Sony will definitely be pleased as it aims to close the gap on Nintendo's market-leading DS Lite.
