Not really.
You might get better specs, yes - But the biggest drawback to new Windows laptops now is, 99% don't come equip with FireWire ports, which most good interfaces use. Unless you're only recording a few tracks via USB, or you're running something like a Fireface UFX, you're not going to be able to use most multi-channel interfaces with a new Windows laptop, which makes them pretty much useless for audio work.
I'm a BIG Windows guy and I will be the first to admit that if you're going to do mobile recording, a Mac laptop is probably the best idea. If you can stand to bring a tower, then it's really up to you, but that's not very portable.
