No, but it won't be more than about a million.

There's more than the XO-1 though.

Contrary to what Tony said, the XO-1 is only 45% of the XO laptops
produced.  The others are XO-1.5, XO-1.75 and XO-4.

Brings it up to not more than about 2.5 million.

Knowing the upper bound should help.

My estimate of XO-1s destroyed or disposed of due to old age; is
about 50%.  The bell curve of normal distributions of end of life for
the components will give a kind of cliff edge for the XO-1.

Don't know.

No, but the XO laptop has been a large part of developer targeting.

OLPC continues supporting XO laptops with Sugar, and where Sugar
departs from compatibility with XO laptops we will maintain a source

We've already reached that point.  The Sugar on OLPC OS 13.2.7 has
some features changed to be a better fit for the XO-1.

Thanks for the photograph.

You'll have a problem because it is running Q2E41 firmware.  You must
upgrade the firmware first, and then upgrade the operating system.
