Apple's deal with Cobb County schools hangs in the balance tonight as the decision faces a critical vote.

The county has already voted to proceed with the scheme, but the vote tonight will declare the contractual liabilities on both parties in the event of breach of contract.

Atlanta Journal-Constitution reports: "The school system wants Apple to be liable for all costs above the purchase price should something major go wrong. Apple insists, however, that its liability be limited."

The board seems likely to agree a compromise position, the report suggests.

The first phase of the plan will furnish iBooks to over 7,100 teachers next school year, as well as upgrade middle school computer labs and fund a pilot program in four high schools.

"The program eventually could distribute 63,000 Apple iBook laptops to all county teachers and all students in grades 6-12," the Atlanta Journal-Constitution reports.
