USB 2.0 support for both the Edirol UA-1000 and UA101 are good news for multitrack audio recording in OS X Tiger. Edirol previously announced updated support for Windows x64, so it's apparent they are continuing to commit to both platforms in spite of the new Pro Tools merger with M-Audio.
From the announcement: "EDIROL today previewed the world’s first professional Hi - Speed USB (USB 2.0) multi-channel audio support for Apple Mac OS X Tiger using it’s UA-1000 and UA-101 USB 2.0 Audio Interfaces. This eagerly awaited Mac OS X support is made possible due to advances made in Tiger, the latest version of Mac OS X and EDIROL’s continued USB 2.0 audio development."
M-audio is on a roll with new hardware priced to meet the needs of enthusiasts who step beyond dipping a toe in to try music creation and are ready to get serious about creativity. The iControl connects to a Mac via USB, providing hardware control over individual functions in GarageBand. 8 sets of Mute/Solo/Record buttons provide direct control over individual tracks in GarageBand. 8 individual rotary encoders provide assignable access to volume, stereo panning or auxiliary bus functions. A jog wheel makes shuttling through long tracks to find the right position a breeze. A MIDI connector provides an interface for connecting MIDI keyboards to the iControl for instrument playback in GarageBand. Record and playback functions are assigned individual buttons to eliminate cumbersome mouse clicks during the editing process. It's like a ProTools mixing desk for the masses.
