I've been reading up on the Nexus 7 and the possibilities it beholds and apparently it used to be able to allow a person to connect the tablet to a TV via a HDMI cable and a mini-USB to HDMI converter cable! This functionality is no longer available but there seems to be some questions about whether this can be overcome with the right software. Anyone able to shed more light on this?
Also for those with a Nokia N8 before, you will remember that it had the ability not just to output to a TV screen but also connect a thumb drive to provide USB on the go. This is also not possible with the Nexus 7.
However, there is one thing that they reckon works which I haven't tried yet. Apparently you CAN connect a mouse or keyboard to the Nexus 7 via a mini-USB to USB converter and a USB keyboard/mouse. Have fun exploring the possibilities and report back what you can do with that little USB port of mine.
