The US State of Maine hopes to maintain its one-on-one laptop scheme beyond its original four-year contract.

It will cost $8 million to continue the existing scheme, or $10 million to sign a similar deal for a year and to replace all 34,000 Macs presently used.

Maine's education department will put a four-year scheme out to bid, but if no better offer emerges will simply extend its existing deal with its existing supplier - Apple.
