Education officials in the nation's second-largest school district are working to reboot a $1 billion plan to put an iPad in the hands of each of their 650,000 students after an embarrassing glitch emerged when the first round of tablets went out.

Instead of solving or doing English homework, as administrators envisioned, more than 300 Los Angeles Unified School District students promptly cracked the security settings and started tweeting, posting to Facebook and playing video games.

Such problems have both critics and supporters questioning whether LAUSD officials were being hasty or overreaching in their attempt to distribute iPads throughout the district's more than 1,000 campuses by next year.
