Hi boyo1991, let me share my experience and give you a different perspective.
I have been a long time supporter of Android, since my first Android device....the Fascinate (or the first Galaxy S). When I needed to buy a tablet to replace my laptop for normal use (similar to what you are trying to do), naturally I bought the Galaxy Tab 10.1 and I spent about $750 for it (I don't mind paying that price as I insist all my mobile devices to have 4G. I do not use public WiFi because it is not safe). I cannot be more disappointed. The battery life is horrible (and I am experiencing the same battery life issue with my GS3 as well) to the point that I stop using it. In my humble opinion, all the fancy features on the device are pointless if the battery life is not long enough for you to enjoy them.
I therefore pulled the trigger and spent another $700 or so to buy the iPad 4 (with 4G). I cannot be happier. The battery life is fantastic. The fact that the battery life does not decrease when I am not using the device is very very important. I hardly lose any battery power when my iPad is not in use. On the other hand, both my Galaxy S phone and my Galaxy Tab lose about 10% of battery life in each hour when I am not using them. I know what you are going to say, I have the same apps in my iPad as in my Galaxy Tab. So it is not the apps. The problem I believe is the operating system and how it manages the resources.
Another thing I have found is very interesting. Some Google application actually work better in iOS than in Android. For example, when I open my Gmail message, I cannot assign it to a label until I close the message which is not very intuitive and very inconvenient. On the other hand, I can assign label when my Gmail message is open in my iPad which is what it should be.
My ecosystem is primarily Google, except my music which are on iTunes. But I don't restrict myself to just Android devices after my adventure on switching from Galaxy Tab to iPad. So I think you should not shut your door prematurely.
Speaking as a Google fan, I think both Google and Samsung should take notes on this.
Hope this helps.
