I'd say unless you need the extra screen resolution then go for the touch screen. Traktor's layout looks perfectly fine on my 15 inch laptop running at 1366x768 and adding a touch screen can only improve your experience with it in my opinion. My only concern would be the actual quality of the touch screen, if it's on par with apple devices then you'll have a blast, but I've seen some very unresponsive screens on windows all-in-one desktops, so it's a gamble I guess.
