Now personally the $100 Laptop Project & One Laptop per Child Project is the most hyped and useless project in the recent times.
The team is impressive (now that Intel has joined the bandwagon) with 11 companies, including Google and Red Hat, which are partners in the OLPC scheme. A great philanthropy act but who will benefit it ? One may ask would money and resources be better spent in building schools and donating public computers. But this seem more like Tech show-off than for any practical good. A great opportunity for tech big weights to show off.
