Alienware is no slouch when it comes to cranking out high-end gaming PCs, but its approach to Valve's Steam Machine project is a bit different. The company is looking to deliver a high-quality PC gaming experience to the living room, but the execution doesn't sound much different from the experience that's already available for other machines running Valve's made-for-TV Big Picture Mode (BPM). The rub of the Alienware Alpha series is that the diminutive PC boots directly into BPM automatically after hitting the rig's power button. The problem with that is two-fold: Big Picture Mode doesn't do the best job of identifying which games are fully controller supported, and because Valve recently delayed its in-house designed controller (which essentially is a stand-in for a mouse), OEMs not delaying hardware of their own need to come up with work arounds.
