I recently got an ipad2, and would love to connect it to my HDTV. (I assume that the Apple HDMI connector is the cheapest and easiest way btw?)
Since the iPad can connect wirelessly to an Apple TV, Ive thought about getting one of those, esp since I could also use it to stream some of the movies Ive saved on my PC, and the Apple TV is one of the cheapest streaming options.
BUT... I would also love to connect my Android tablet and Android phones to the TV wirelessly. Could I use the ATV for that? For example if it was jailbroken? Both of my phones and tablets have built in DLNA, but I'm not sure whether the ATV has that, or if it uses another method to connect to the ipad?
I would suggest picking an ecosystem and sticking with it. Getting all Android products allows them to all work together as designed
Getting all Apple products; Apple TV, iPhone, iPad, and Mac, allows all of them to work together perfectly, as designed. Apple uses iCloud and AirPlay to allow all their devices to interact seamlessly.
These technologies are all meant to work together with what they are designed for. I understand your desire to have the best technology with the iPad, but sticking with a PC and Android will definitely cause issues when trying to use the 2 platforms in conjunction.
