No, that's not what I'm saying. Mirroring a mobile device and a computer are different things. For each you need the newer processor
There is no conspiracy, it's a hardware limitation.

Wait, you mean to tell me that Apple's a5 procesor is somehow more equiped to handle video encoding than a 2.9GHz quad core intel i7? That seems strang to me. Personally, I think its just Apples way of forcing people to buy new hardware.
I used to think the same until i found the Intel video features sported by recent chips - presumably with a similar hardware enhancement in the newer iOS devices.
Ultimately Airplay is a protocol which transmits video/audio across the network.
The transmitted stream could theoretically be software or hardware encoded - Apple seems to have limited availability to hardware capable devices - Airplay attempts this in hardware with varying degrees of success in different systems.
I am not very keen on Airplay - perhaps I'm just sore that none of my Macs (2008 8 core Mac Pro for example) support it - butat best it is a compromise due to the on the fly compression required for mirroring and quality adapting to bandwidth availability on the LAN. I have no doubt for many it works well, especially maybe for mirroing fairly static desktops, but the compromises will be more noticeable with rapdily changing video frames. Even though iTunes store 1080p only requires 8 Mbps or so bandwidth, that video will be pre-rendered with quality not onthe fly using corner cutting algorithms (software solutions allow you to tweak quality downwards to improve lag and vido performance).
Also I'm not really sure what I'd Airplay - DVD player on a Mac won't Airplay for example as the frames are protected at low level to prevent copy circumvention by intercepting and decoding Airplay.
