I am a Shuttle fan but believe that they have made some critical mistakes in the direction they have taken with respect to the video output feature set for their recent products.
First complaint I have is the Shuttle XPC X100/X200. It is a great design and the DVI connector was the right decision, but they forgot to equip it with dual outs. Thus it loses out to the Acer Veriton 1000/Aspire L3x0 series which feature 1 DVI + 1 VGA outputs. I opted in favor of Acer's offering primarily because of this.
Next is their new G6 chassis which is just gorgeous (fingerprint readers are becoming de rigueur), but the MAJOR boo-boo here is that they opt to put in VGA + HDMI output when it should have been DVI + DVI or DVI + HDMI! VGA is already obsolete and does not belong in an otherwise bleeding edge design. HDMI monitors are still impractically expensive.
People hate being forced into DRM technologies and I'm sure quite a few hope that HDMI will prove to be a failure.
