That would correspond to HP's ZBook or EliteBook lines. They do have genuine 2x2 multi-antenna setups. There's nothing "Pro" about a $775 "ProBook".
Lenovo makes more business-oriented laptops in general, but the Ideapads are definitely their low-end (and come with 1x1 antennas - found at least one with a single antenna and dual-band wireless chip [1]). The Thinkpad T-series portables or W- (now P-series) workstations are definitely the way you want to go. And they do have genuine multi-channel Wifi solutions.
