Reply to Buying a new laptop that will persevere through Traktor's bulky software updates

I just bought a new 13.3-inch MacBook Pro (2.9GHz dual-core model). Specs are as follows:


I've bought this to replace a Dell Studio 1555, which turned out to be a ongoing evening mare to use with Traktor throughout the three years I used it. (That's what I get for buying such a weak machine at the time.) And to top things off, a few software updates ago, Traktor Pro 2 became unusable due to a CPU load latency issue, even though the machine still falls within the TP2 system requirements.

I'm hoping this MacBook will serve as a solid Traktor-compatible machine and persevere through four or five years of bulky Traktor updates. I have 14 days to return the MacBook so should I choose. My main concern is resolution. This machine has about the same resolution as my old Dell Studio. The MacBook is not a Retina Display model. The Studio's res was adequate for TP1's interface, but TP2 is very cramped.

Should we expect NI to continue to require more and more display real estate for Traktor as the updates roll out, or might they begin to streamline their interface more to suit displays with less real estate to spare?

Also, given how processor-intensive Traktor is getting, how long would you estimate a 2.9 GHz Intel dual core i7 processor to be able to handle Traktor throughout all the updates and new versions? Three years? Four? Five? Does anyone believe quad core is necessary for longevity, or will dual core get it done for a while?

I'd appreciate your thoughts!
