On the money on parts but perhaps a little unfair on software. Rabbit R1 (and Humane) both needed beta testers, not product reviewers. Had they offered these devices at cost for people to participate in a public beta all the negative press might never have appeared. "Of course it doesn't work properly; its in beta." the CEO would say on The Verge and nobody would question it.

OLPC kinda failed because they failed to provide training and tech support. The actual product wasn't bad but teachers didn't know what to do with them. They did also fulfil all their 'buy 1, get 1' orders to western customers.

Ironic though that in the end it would be a little single-board computer from the UK with its roots in 1980's british software that would enable computer science across the world :)
