Re: "I advocate them for professionals"
"Games aren't high performance" - yeah, but I can't use that argument. I just can't recommend what is essentially marketed as a gaming rig to the R&D, engineering and scientific research crowd. That just won't fly where I work sorry.
As Mr Pott has commented in a previous post, a lot of it does come down to what apps you need to run and I'll add, the business environment where you are running these demanding apps. There are many places where Alienware will do just fine, more than fine (and better than a "workstation" even in some cases). But there are places where a gaming rig is just not appropriate, for various reasons, e.g. environmental constraints, corporate policy, certification requirements, corporate IT requirements (think ease of provisioning, deployment, re-imaging, remote management across a fleet of mobile workstations), security features that just aren't available in consumer devices.
Anyways, Alienware and Precisions don't really compete in the same markets so arguing which is better is kinda pointless. Both have their place in the world of high end mobile computing.
