I bought Logic 8 Education £118.00(Academic) the day BEFORE Logic 9 became available :-(
I had Logic 8 with the shrink wrap off (delivered in 24hrs), when i saw that Logic 9 was out...W.T.F.
I purchased from the Apple Store U.K. online.
When i contacted them they offered me a further £30 discount OR
a full replacement to Logic 9 ....... I took Logic 9
The info i have is that there is NO upgrade path from Logic 8 Education (Academic) to Logic 9. You have to purchase Logic 9 again (£118.00)
By the way, i also found out (thanks to interwebs) that Logic 9 ships with NO hard copies of the Logic Manuals... it comes with an update booklet and html on the DVD.
The Manual is available to purchase from the Apple store (20 or 30 Dollars i think)
With this info i contacted them again and asked if i could keep the Manuals from the Logic 8 packaged box (as i had opened it)
No problem, was the reply
What a difference a Day makes.
Also there is a Store in the U.K. selling Logic 9 at the same £118
Apple Logic Studio 9 - EDUCATION PRICE
As i purchased from the Apple Store online, i would think this applies Worldwide.
