The people who keep saying "If you need a mouse, get a laptop" are stuck in a time warp.
Adding mouse support to the iPad is optional. No one is saying the touch interface needs to go...it will always be there, front and center.
But if someone wanted to pair a mouse, it opens up a whole range of possibilities.
If you can't see that, well ok then. But it would.
I believe it's the other way around. People that say the iPad Pros need mouse support are stuck in a time warp. The times are changing, and mouse support is quickly going away. Right now if you need a computing device on the go, a laptop is your choice. All the 2 and 1s are neither great at being a full fledged computer or being a tablet. Apple is laying the ground work for the future, and it does not have mouse support in its future. Watch things like excel for the iPad will become way more usable with a touch screen. Just like everything else Apple adopts or makes standard, it becomes the standard. iOS is not built for mouse support and never will it be.
