@eliyahuHi. Yes, the Pet has been delivered, shipped and sold out. Now there's a new model, the Leo, which is better crafted than the Pet and less expensive.
@HypexCommodore's compuyers also ran GEOS which had nothing to do with MS. As a former Windows Phone user, I'd frankly say nothing should ever run such a poor excuse of a mobile os.
The embedded version of GEOS (For PCs - called breadbox) was actually licensed to Nokia for its phones. https://sites.google.com/site/geosresource/geos-archives/breadbox-other/about-breadbox
