Well, the trick to saving RT, I believe, is to educate people what's the difference between RT and windows 8.
My first MS hybrid was an RT device. I was pretty happy with it, actually. Most of the criticisms of the RT devices I dare say are invalid, because they demonstrate a gross misunderstanding of what RT is. You really have to try to use it in real life to appreciate how well these devices are compared to android and iOS. People often complain that RT devices don't run legacy apps. When iOS came out, I don't remember anyone complaining that it couldn't run Mac apps.
The reason I think RT has failed isn't because of how capable or incapable the OS is, but because of people's ignorance.
As I was saying, I was pretty happy with my RT device. Then one day I needed to print out something. Was too lazy to drag my ass upstairs to the home office to the PC. So, I tried to connect my RT device to the wireless printer. Says no driver in the list for this printer. Annoyed, I went and plugged in the usb and searched for drivers. Again, none was found. I called Samsung (maker of my printer) tech support. The first tech support guy kept linking me to the windows 8 driver for the printer. I kept telling him I had the RT. He then said something that made my jaw dropped. He said RT and 8 were the same thing, so driver for one should work for the other. I spent about 10 minutes trying to explain to him the differences between RT, mainly the processor architecture. He was unconvinced because after all he's the techie and I was suppose to be the ignorant tech illiterate.
I finally asked to speak to another tech guy. So, he transferred me to someone else. I explain to this second guy the situation and I needed driver for this Samsung printer compiled for RT. He linked me to the windows 8 driver and told me 8 and RT were the same so I could just double click on the exe file. Again, I tried to explain to him the difference between RT and 8 and he kept insisting over the phone that RT and 8 were the same and he was the tech guy between the 2 of us.
I politely thanked him and hung up.
I still needed printing support for my RT device, so I decided to go to MS for help. Couldn't find a number, but I did find an email. So, I emailed MS for help on this. I wrote out a very detailed explanation of what I needed. I know these guys are busy playing video games all day, so I even summarized what I needed in an easy to read table.
Got a reply the next day from an MS tech support. He linked me to the printer driver built for windows 8. I replied reminding him that I had an RT device, not 8. The next reply from him was jaw dropping.
Now, remember that this was coming from an MS tech support, not some backwatered office in Africa.
The MS tech guy replied to me telling me RT was the same as windows 8 and that the exe file he linked me to should work for both RT and 8.
I was speechless, so I wasn't able to formulate a reply. Later that day, I got another reply from him. This time, he apologized for the "misunderstanding" and said he could not find a driver for me built for RT. I think someone must have told him his mistake.
I'm talking about 2 Samsung tech support people and 1 MS tech support. They all insisted that RT and 8 were the same and that apps compiled for one would work in the other. And I was the guy seeking help. Any other person calling in would have been like the blind leading the blind.
RT has no future. Regular people don't know the difference between RT and 8. And tech companies don't know the difference between RT and 8 so there's no manufacturer support for RT. Heck, even MS personnel don't know the difference between RT and 8, so good luck trying to get adequate support for RT.
RT is destined to die a meaningless death because the clowns at MS decided not to educate people properly on what RT is.
