Yes but the iPhone and iPad are not Mac's, they were built for Touch in mind (hence iOS) Touch on computer is not a great thing, the Surface isn't better than an iPad at being and tablet nor is it better than a Mac at being a computer because it's trying to do be 2 different things. And your comment about "what's expected" is going against everything that Apple has stood for, they don't do what's expected, it ws Steve Jobs who said "people don't know what they want until you give it to them"
Touchscreen on a Mac is a bad idea, iPad's and iPhones are meant for Touch and Mac's are meant for point and click.
Have you had that chance to use a touch screen laptop of any period of time? While I don't find it to be a requirement I find it to be pretty useful. Since I am accustomed to using a phone touching the screen makes a lot of sense. I can tap the [OK] button during installs, launch apps, scroll up and down, all the stuff I do daily on my phone happens on my screen. I don't use it for everything but when I want to use it, generally when doing lazy reading of articles on the web, standard install stuff or testing mobile apps in the emulator, it comes in really handy.
My personal laptop is an Asus 17" with touchscreen. It has 24GB of RAM, 256GB SSD, 1T HDD, full keyboard with numeric keypad. Gives it a number of features I could not get on a Mac laptop all for $1300 USD. I enjoy the touchscreen more than I thought I would.
My work machine is a MacBook Pro, 15", 16GB of RAM, 256GM SSD that is nearly fully. Fine machine but wish I could get a bigger screen, more RAM and a bigger SSD (which is available on the newer models).
