I don't like or trust wireless technologies. They're inherently insecure. They can be hijacked by anyone. (WPS can be hacked in minutes, WPA takes a bit longer, but not by that much. I've had my wireless network hacked numerous times because of WPS.) Adding security measures makes it harder to work with, so many people of the general public object to the security necessary to have decent wireless technologies. (Thus the problems with WPS.) On top of that, they get interference from many sources and disconnect or work slowly. Wireless charging is ok, and I could live with that, but wireless networking is a pain in the behind. The only reason I have it is to run my tablet. I've got it isolated from my main network because it is so insecure. Wireless Display looks like a horrible ides that would be horrible to support.

WPA2 + AES is far more secure and should be the standard for any wireless network being set up today. Cracking WPA2 + AES would take an absurdly long time (many months if not years) and would require some serious hardware to complete the task. WPS should absolutely be disabled as it doesn't make connecting devices any easier and is a security nightmare.

802.11ac devices are much faster and less susceptible to interference than older 802.11g and even 802.11n equipment. Wired ethernet is still king for reliability and throughput but not everyone can or wants to run ethernet cables to the locations of all of their devices. Newer standards and equipment have come a long way in the past few years.

to put wireless charging solutions in consumer products in stores and restaurants.
no store or restaurants are going to want to add expenses of these fool tools and increased power bills when they are squeezing every penny already.

this would be better implemented at kiddie schools where kids have no concept of charging devices or can't be trusted not to put sockets or plug-ins in their mouths. it would be great for hospitals and business where there isn't time nor outlets to deal with cords and their clutter.

as far as wireless information transmission the NSA/law enforcement is going to love this, more free access to everything, no court order required. same with competing companies and foreign governments spy agencies.

1. WPA2 is fairly easy to crack with either a monitoring log, where the encryption keys are exchanged every two hours or through using a GPU to decrypt the data. Since WPA reconnects and exchanges keys so often, just monitoring the data at the right time will allow a listener to get the keys and get in. GPU decryption has made decrypting data where you don't have they key far quicker. With a 4 or 6 core CPU, it would take years to decrypt, but with a GPU with 1536 simple processors, it comes down to hours.

2. WPS is found on all consumer level routers and access point on both Wireless N and AC. In order to get a wireless access point without WPS, a person has to spend about ten times as much for a commercial router. What's more is that while is can be "disabled" on most routers, they all keep the code active, and a hacker can still get in using the PIN. It takes getting an open source router and putting on a special version of the firmware that completely disables the WPS code to actually turn it off. It's horrible.

3. I have a dual band Wireless N router in my bedroom with 6 antennas. Not ten feet away, in the same room, I have two tablets and two phones that use both bands. My work iPhone and my android tablet use the 2.4GHz band, while my Windows phone and Windows RT tablet use the 5GHz band. None of them can connect at higher than 60Mb, and all of them have problems disconnecting when I walk out of the room. I have tried tuning the router channels in several suggested ways, and the power of the router is at maximum. Yet, I still can't get it higher than 60Mb, and they still like to disconnect. I have turned it off on my personal phone specifically because of the disconnection problems. The big reason behind it all is that I live in an apartment complex with several hundred other people. I can see over 100 wireless networks from my tablet at any given time. So, we're basically all stomping on each others' feet, wirelessly. I will always prefer wired networks. I never get this type of problem from a wired network.

I think wireless charging will be a more widespread standard in a few years, especially if Apple hops on board the wireless charging train. If the next generation of iPhones and iPads support wireless charging then there will be several manufacturers adopting whatever standard they choose (unless it's some proprietary nonsense). Starbucks, McCafe, and other similar chains will then start installing these wireless charging grids under their tables and counters and people will just put their phones on the table and top off the batteries as they sip their lattes. When the time comes that wireless charging is standard in new devices a manufacturer of these charging pads will pair up with the restaurants and start subsidizing the cost of the charging pads and installation. The cost will be very low for restaurants and the benefit to customers will be easy to sell.

WiGig is not viable in locations with user density above 5-10.
Heard this right from Dell.

No switch or automatic hopping on device to diversify frequencies.
Terrible for cube farms.
