Why would this be? This seems like one of the default apps that people would use the iPad for. Waiting for enlightenment.
From what I understand there are 2 reasons. The technical reason is that a single app can be very easily updated with new features, fixes, etc. much easier than having to download and install a complete OS update as is the case with the "standard" bundled apps such as on the iPhone. I believe a bigger reason for doing this is to make companies like Amazon a little less inclined to scream. Since you'll have to search out and download the reader application, Amazon will have "equal footing" when the release their Kindle app for the iPad, which I'm certain will be ready to go on launch day.
Do you have a source for your statement, so that others may read too what your subject is about? My Thoughts are it will be part of iTunes in the way of a helper app. My own iTunes app has been moved so far from my home screen on the iPhones I use, since I mainly purchase or obtain my apps via iTunes. The iBookstore however once on my iPad, will be my main source for both searching and buying books from the store, not via iBookstore in iTunes.
9 to 5 Mac Here is the link that prompted my question. I found it on 9 to 5 Mac. I actually copied and pasted the title of this thread from that website article. iPad doesn't ship with iBookstore by default | 9 to 5 Mac
If keeping it a separate app makes it easier to update it with newer features at a faster pace, I'm all for it
It also neatly avoids the IE entrapment argument and anti-trust (we know the EU is big on hitting US corps with that book. Not that I object )
I totally agree with both points made, particularly the second point regarding "equal footing". This is a very smart move on Apple's part because it basically avoids all potential law suits regarding fair play. Competition is good for everyone and everyone wins.
