Reply to Any users of Traktor DJ Performance thoughts on iPad2 vs. iPad w/ Retina display

So...I have been on the verge of acquiring an iPad for a while and am almost ready to pull the trigger. With the Traktor DJ app now out, I will definitely be getting it (can't beat the price).

My question is for any owners of the iPad 2 vs. iPad w/ retina display, what are the performance comparisons? iPad 2 is cheaper, but potentially slower and only comes in 16GB, but is only $399...iPad w/ Retina is potentially faster and comes in 16GB ($499) & 32 GB($599). Is there any performance lag, slowdown etc. on the iPad 2? Is it worth the extra $100 to get the newer iPad? is it worth the extra $200 to get the newer iPad with 32 GB? I am not sure that I can do $599...I can do $399 and maybe $499...but that $599 may be out of reach...

But if it is worth it...I may try to make it work.

Oh...btw, my current setup is: DN-X1700 + 2 TTs w/ timecode + 2 CDJs (not timecode) + Kontrol X1 as my at home setup and a DN-MC3000 and Kontrol F1 as my portable setup. The iPad would be mainly used for other stuff, but Traktor DJ will be a nice bonus.

Any thoughts.
