To actually answer your question if you don't want to try my Mac:
If I were looking in the price range of the smallest Macbook Pro, I would also look at the vastly superior (in technology and specification, not talking about the operating system. That's still to each his own.) MSI here:
MSI GS Series GS60 Ghost Pro-002 Gaming Laptop 6th Generation Intel Core i7 6700HQ (2.60 GHz) 16 GB Memory 1 TB HDD 128 GB SSD NVIDIA GeForce GTX 970M 3 GB GDDR5 15.6" Windows 10 Home 64-Bit - Newegg.com
Though I do believe you'll have to wait about a week, I don't think the 'Skylake' i7 is released yet.
This is only because it's in the same price range as the smallest Macbook Pro, this is way more computer than you need with the current software.
You don't need the graphics card, but if you play games you'll be happy you have one of the best and it offers you both a mini-Displayport and a mini HDMI for multiple screens. With an external mouse and keyboard this could serve as a very powerful desktop too.
DDR4 ram is still very new and very fast and will handle plugins better, plus there is 16GB of it which is a lot right now, expandable to 64 if virtual reality ever comes out or the Oculus Rift makes it to a laptop. I can't think of any reason to use that much ram.
It has a small solid state hard drive for the operating system and quite a few main programs and then also a large regular hard drive for samples, music, movies, etc.
This is a beast. Even for a desktop. And with the ability to run at least two monitors with the HDMI and Displayport, probably 3, maybe 4 with the Displayport, with an external mouse and keyboard, just shut the top and put it off to the side and it'll be just like having a really powerful desktop.
There are steps down from this of course. I would tend to stay in the gaming area even though you don't necessarily need the card. Though it wouldn't hurt if you want to use more displays to run a web browser, your DAW, and your plugins at the same time.
But the gaming laptops (and computers, in general) tend to have everything else you'll want. (Or, a workstation would too, but there's no reason to pay for it if you watch the video I posted earlier, you won't need ECC ram or error correcting RAIDs.)
Like everyone has said, eight gigs of ram is where you want to start, more if you can afford it.
i7 or i5 doesn't matter unless the i5 doesn't have hyper threading, watch for that. It's basically double the number of processors. The amount of cores is essential to multi-tasking and I count plugins and addons as mini programs and so that counts as multi tasking.
The newest generation of Macbook Pros look really good too though. The price is around double for whatever you get.
