Microsoft is still refusing to talk official numbers, but the real impact of the shortfall in Surface tablet sales has been revealed in the company's latest earnings report.
While overall Microsoft continues to chug along like the tech giant it is, the latest financial state of play shows a massive $900m loss on “inventory adjustments” caused by unsold Surface stock.
It's all tied into the heavy price cuts Microsoft has announced recently to try and boost the Surface's sales momentum, particularly the little-loved Surface RT.
Prices of Microsoft's debut tablet have dropped by £120 across the board in the UK, and $150 in the US, with the cuts mirrored in other markets too. Effectively, that means the total value of existing Surface stock has dropped – and dropped a lot, it seems.
Microsoft has structured things so that the loss is absorbed by its total Windows revenue for the quarter, which fortunately was quite healthy otherwise.
But it does suggest that there are still many millions of unsold Surfaces out there in the wild, and they're not going to get any easier to shift – especially with rumours already talking about a second-generation wave of devices running Windows 8.1 and Windows RT 8.1.
