I am looking to purchase a tablet, but I am hesitant because I know nothing about it. I wanted to know if android/ android 4.0 OS would allow me to download applications onto the drive? For example I use an external harddrive to store my documents music and movies. Will I be able to download programs to work spreadsheets, watch different video formats on VLC media player, will it support the use of my external harddrives, do they all use stylus'? Am I able to download anything from the internet and run and load it on the OS is my main question. Thank you for help in advance. Any references for the device im looking for would be appreciated but if you point me in the right direction I'll find it.
