Note 3. USB keyboard & mouse connection via USB hub works well. USB Drive 16 GB OK. Panasonic Camera OK too (in fact everything is as FAT32 disk). My external drive 500GB NTFS will not mount but I expected that. It seems that Android does not want ... Login flawless HDMI display too. Also interesting to note that with keyboard and mouse connected HDMI display automatically switches to landscape mode with the home screen dock, but if I take them, I stay in portrait ... Good definition video with the Samsung App Video . OfficeSuite also works well (except the size of the menu bar which is huge big screen)! Good buy.
