Can you show me where I called people "stupid"? And no, I don't work for Apple and I am not an Apple plant. I just try to help people here and have done so frequently. I may have been sarcastic with some people but they appeared to be trolls, not people actually trying to get help.
People who aren't in the industry do indeed buy computers every 15 months; most people in the "industry" do not do so because of budgets.
I don't recall telling you that there was some feature you were missing. I probably did mention Airparrot. And any reasonable person would know that 3rd party software is not "supported" by Apple. Microsoft Office is also not "supported" by Apple. Microsoft supports it.
I have Uverse. My nephew installed Uverse. All of us have 802.11n speed with the 2Wire router. And why do you have a router behind the router? If you have a piece of equipment that does not have N speed it will reduce the speed of your network. But the 2Wire router does support 802.11N. Your main consensu is wrong.
Yes, there are complaints about AirParrot as it so heavily relies on the processor to perform. If you have an older processor it doesn't do so well, a newer one (ironically like the latest Intel processors). It performs better. It pretty much takes over the processor and can turn up the heat on the computer very quickly. This is why Apple chose not to go this route for mirroring.
Not going to get into all the "Apple is proprietary...", etc. ranting. I am assuming no one forced you to buy anything. As far as your "upgrade or you are left behind", and PCs, if you go an buy one of the latest PCs you can indeed get "AirPlay Mirroring". Only it isn't called that, it is called Quick Sync, which is what Intel called it and it is their chipset HARDWARE feature. Apple is not the only company using it. You can read about it from the source here: http://www.intel.com/content/www/us/en/architecture-and-technology/quick-sync-vi deo/quick-sync-video-general.html
Even PCs that are 15 months old do not have access to this feature. You have to buy machines with the latest Intel processors/chipsets.
If you have heard me all these times you should not have any trouble understanding that the only way you can get Quick Sync (Airplay Mirroring) on an older Mac would be to replace the processor/chipset/GPU on your computer. Do you really think Apple should do this for you? Honestly?
So if you need mirroring get someone to help you straighten out your Uverse WiFi situation and buy AirParrot. Or buy ANY computer that has the latest Intel processor/chipset and use Quick Sync. If you get one of the latest Lenovo machines you can also get Thunderbolt.
