HP's drastic price drops for the TouchPad helped make it the top selling non-Apple tablet in the United States this year, according to research group NPD.

The top non-Apple spot in the US however came at a hefty price for HP, which revealed yesterday that it wrote off about $1.6 billion winding down the webOS hardware this August.
This included a $142 million hit from TouchPad discounts, $548 million in supplier-related obligations and $98 million in restructuring charges, according to a Seeking Alpha transcript.

The latest discount puts the 16GB device's sale price at just $US9 above its $US190 cost in materials, according to a teardown by UBM TechInsights.
