Some of them are, but not all of them.
The android phone has some of the same apps, but not all, vice versa.
Apple is too good for Android to take their apps directly. Their display would look weird on their devices anyway.
It depends.
Most apps which are on the kindle are usually on the android or the apple store.
Obviously, The best place to for android apps is android market place. The official platform to download every app of android but not those which were suspended because for violating rules. Many good apps were suspended from Android market just because of policy issues even people liked those apps a lot but still they did it. On the whole one can find more than 85% android apps on Android market place.
Yes they both support the same apps as they both run on android, for good galaxy s2 apps try
There are both free and paid apps available for android phones.
