The computer industry used the DVI port for digital quality displays (Left side). The consumer industry (TV's etc) decided the DVI port was too big to fit in the sides of slimline TV's and therefore turned towards the HDMI port (Right side). The HDMI port incorporated the Audio whereas the DVI required a separate cable. Electrically the signals were compatible so it is possible to buy a DVI to HDMI cable and run a separate Audio cable for connecting a HDMI device to a DVI device. This is useful for connecting DVD / USB players to computers / monitors and vice versa.
Android 4.0 (Icecream) runs well on a 7" Laptop. I am now running my Asus 7" Netbook on this operating system which does not have a 'Touchscreen' and has only 500Mb ram. My system boots in under 30 secs and surfs the web in a fast HTML 5 Browser. Youtubes work perfectly as does picture viewing. Movies need to be MP4's. Google marketplace is usable but care has to be taken in selecting apps as a laptop can only be run in 'Landscape mode'. I use an external mouse similar to the picture shown. Wordprocessing is achieved with Google Docs. The software requires the use of wireless only. My built in camera worked well with Skype. Virus checking and updates not required.
