It's not. Really, it's not.
You can use the trackpad either as a pointing device or as a set of media-control touch-sensitive buttons, but not at the same time. This feature is toggled via a gigantic button placed between the two main mouse buttons. That means you can accidentally enable the media control keys all too easily, and suddenly your mouse isn't responsive. Unless you're looking at the trackpad, you won't know why. Luckily, the big volume-control wheel directly beneath the trackpad works whether or not the media-control feature is enabled.
The handling of standard-definition video scaled up to the full 1080p resolution of the screen is a mixed bag. DVD playback seems noisy, though edge enhancement is thankfully minimal. Blu-ray high-definition playback looks much better, but overall video quality is still a touch soft.
Audio sounds fairly good through the built-in speakers. Acer ships this model with Dolby audio-enhancement software, which helps movie playback substantially--the virtual surround sound works fairly well, though the surround "speakers" are still more front than rear. You still don't get much bass, though, so low-frequency effects are often missing. Music playback is less robust. In stereo mode, vocals take on a dirty, edgy quality, though the speakers sound fairly good in pop and rock.
The Acer 8950G is a capable digital media system that can handle current-generation DirectX 11 games if you're willing to dial down detail settings a bit. High-definition playback is generally pretty good, but not exceptional. At roughly $1500 as configured (price as of June 7, 2011), it's a balanced set of compromises that falls short of perfection, but gets the job done.
