I don't have one but have looked over the shoulder of guys using the Ipad for manuals. Its the dog's, and very readable. As with most electronic books the indexing is poor (done by software rather than by a professional indexer?) but that's the editors not the Ipad.
Not sure if it handles the automatic amendment system but you can always re-load each time you come through the Street.
And it does all the rest of the Got-To-Have stuff as well
