Gamertell has posted a mixed review of Gamertell Review: Guitar Hero On Tour for the Nintendo DS. From the review:
"The touchscreen is great for natural style strumming... The DS also makes for some nice special moves including physically blowing into the microphone to put out fiery attacks and signing the screen when a fan runs by and begs for a song-interrupting autograph...
Physically, the DS looks pretty kick-ass with the four-button Grip attachment. Unfortunately, that bit of innovation is also a wrist-wrenching, ergonomic mess...
Playing for 20 minutes is nearly impossible unless you're able to endure a fair amount of pain or you have otherwise numbed your arm. You'll need to suffer through it and risk carpal tunnel syndrome to play more than a few songs at a time and get in any significant practice."
