Are there iBook apps for Android tablets?
Are there iBook apps for Android tablets or PCs? I don't think it matters, but I have a SAMSUNG 4 tablet and Dell Inspiron laptop. Are there any other eReader apps that can read iBooks books?
No, there are only iBooks apps for iOS devices and Mac computers.
You might be able to read some ibooks on android, but the majority of ibooks have digital rights management on them which tie them to the iBooks apps - publishers such as O'Reilly don't include DRM, and free ibooks may not have DRM.
If you want to be sure of being able to read them on your android and/or PC you should buy them from stores which have android and/or PC apps
