What sort of thoughts do you mean? That's a wide open question. Obviously, many people have posted thoughts in blogs etc. Personally, while I kind of like rd, I can see why some people don't. I know some devs who hate to have the site reflow on different devices. They prefer to zoom in to see what they want. On balance, I prefer the layout to be optimized for the device I'm on, though I hate to have some content unavailable.
The best thing about rd and designing for mobiles is that they've made people realize their desktop sites are full of a lot of unnecessary junk. I hope that the effect will be to stop people loading their sites with this unnecessary content, rather than just use display: none on the mobile version.
This Tweet is a classic:
“Mobile users want to see our menu, hours, and delivery number. Desktop users definitely want this 1mb png of someone smiling at a salad.”
