Now with the iPad I am thinking of finally taking the plunge for Ebooks. I have never used a Ebook reader before so I dont know if Ebooks have different file format ( extensions )... With iBooks ... will it be able to open any Ebooks on the market .. or only books from the iBook store ? Also I am Canadian .. and from what I am hearing .. the iBook app or store wont be available to us when the iPad launches here up north ... Is it the app or the store that wont be available ? If its the app ... what can I use to read eBooks on the iPad ??? ... low rez iphone app ? ... Thanks for showing me the ropes on this subject guys !
