Challenges in personal computers

1. Initial boot up time is too long and wastage of energy and time with no direct benefit .
2. All those wires to connect many devices and accessories create a big wire jungle.
3. Many different type of power supplies( no standardisation in power supply. Why not build all using 12 or 24 volt power coming from the computer( this will eliminate need of many transformers).
4. Make all computers(netbooks and note books) ready for downloading of books and make all the books in public domain available to every body at free download courtesy of library of congress and not for the benefit of Google or others.
