>snip loads of posts about Fred and George being 17, and yet "of 
age"<
I think JKR has done this for a reason. The wizarding world and it's 
laws are hers to create, after all. Passing the Apparation Test at 
17 simply mirrors British laws on driving, and I don't think it's 
contradictory that Percy didn't learn until 18. However, if the 7th 
book follows the structure of the others, it will cut off in June. 
Harry, therefore, will end the series aged 17, and I think his 
being "of age" will certainly be in some way instrumental in the 
final instalment.
