Maybe a little -- but I bet when they do come out with a touch enabled Mac, it'll do things others haven't thought of yet --and-- whatever those new features might be, they're probably already patented... ;-)
I don't think we'll be seeing a touch Mac any time soon.
Apple have the very clear direction about their devices - iPad is tablet, Macbook is laptop. No hybrids.
And it's a very good strategy, clearly MS have struggled to get the hybrid idea right with the backtracking and then no start menu, then no start screen, killing RT before it got traction etc etc. Maybe Windows 10 will solve this problem, may be it won't, time will tell.
But for now, OS X seems to have no potential benefit at all from touch, and has no need to really as people generally seem to own both a Mac and iPad.
Which takes us nicely to the next point - why sell someone one hybrid device, when instead you can then sell two devices and make more money. Simples.
