by theorical, we can transmit electric without wire(wireless) but it will cost more and more... we should make a tranmiter and reciever that will transmit and recieve something that with very low frequency..by formula...(speed)=(frequency)*(wavelength)when speed is constat..then frequency is very low.. wavelength must be very high..very high cost and difficult to design..
livecd is a good os for someone, that just wanna try the OS without install it.. can be direct boot from cd... not only for os trial..its also can be a mobile OS...
before this, i was used suse with KDE, then im try out fedora core 6 with gnome.. the desktop quite same..but Gnome more user friendly even there must be very slow than KDE.. For me, i prefer KDE better than Gnome coz speed is more important.. my laptop only using ram 256.. so that, if i use gnome, my laptop will be too slow and will be hang so many time..
