Well there is also another option.
the Touchsquid app. They recently released an update that works on the G Tab 2's to function their IR blaster.
But it also will work with the Global Cache Devices, IRtrans and there was another system that I dont recall.
I have been using the Touchsquid app on my Asus Transformer ( no built in IR ) along with a iTach Wifi2IR to run my HT set up.
They have 2 versions of the software Home controls I think 4 devices and Pro is basically unlimited.
There is also a Demo version.
I am running 4 Sony CX995's, 1 Panasonic BR Player, Dynex Switch, Colby DTV Tuner, JVC Radio, Sharp DLP TV - Been working great since December
They also have great customer service. And if you are looking for a tablet they also have a Tab with a built in IR Blaster as well.
