I forget — why are we trying so hard to keep XP around?Question 2: What legendary Neil thoroughly dissed the sound quality of CDs? 10 points b. Neil YoungYoung said it at Sun Microsystems’ JavaOne conference while unveiling his upcoming Blu-ray project — five volumes of 10 discs each, covering everything he’s ever done (in beautiful high-definition audio, natch). The record companies’ response: We hope Neil Young will remember — compact discs don’t need him around, anyhow. Question 3: What’s Research in Motion calling its latest smartphone? 10 points b. BlackBerry Bold Bold, yes, but with just a hint of mint. The dingus features 3G speeds, GPS, Wi-Fi, yadda yadda yadda.

Calafia Cafe and Market a Go GoSome three years in the making, the Calafia is scheduled to open its doors in Palo Alto this fall. No word yet how long he’ll keep the “beta” after the name. Question 5: What is not considered a sign of the second coming of the Jesus phone? 10 points d.
