As such, products that implement professional-level MIDI interfaces can and are used to assemble stable and low latency MIDI systems at a much higher cost than your average consumer-level product. However in practice some (most?) MIDI and/or isochronous (typically audio and video) USB subsystem implementations deviate from ideal and could indeed be heard by a trained ear. USB 3.0 won't solve such subsystem implementation issues, and it certainly won't be something available to the average musician for years to come. USB 3.0 will only START becoming available in 2010 and the market in general needs to "Get Real!"; only 2% of those that *want 3.0* will be able to get a suitable SuperSpeed Subsystem -- Host + Device, and maybe a Hub -- in 2010! Then potential users must ask themselves if they are prepared to pay a >50% premium to implement a suitable USB 3.0 device tree? (Such a SuperSpeed configuration could easily have a 100% to 150% cost premium over a similar USB 2.0 implementation.)

Today USB isn't even slightly comparable to iee1394 (Firewire) when it comes to stability and low latency in music applications. I'm a musician and I can perfectly hear the latency of a MIDI interface on USB bus compared to an old gameport one, or even a Firewire. And digital audio is even worse. Please, puhleeze, think of the musicians and do something to reduce latency and dropouts. We don't need just speed.
