[Asus Transformer TF700] HoushaSen:
It is truly your preference between iOS vs. Android ecosystem.

Hardware specs are irrelevant in my opinion as in the end they seem to even out.

1. Screen resolution - Ipad 3 has better resolution on paper and it indeed has but as some reviews suggested the difference is much less noticible than from traditional tablet resolution to Infinity. Whether your eye can truly tell the difference or not, you really have to pull up probably two system side to side, but that's the only time you may notice.

2. CPU - Infinity has better CPU benchmark but GPU is better on iPad 3. Though no game at this point pushes to their limit so it won't probably matter.

3. Camera - Infinity has better camera, but do you really use tablet camera that much? It is never good as that of real digital camera.

4. Battery life - I only have iPad 2 but iPad 3 supposed give the same battery time as iPad 2. So based on this fact, I say iPad 3 should be much better battery life than the Infinity; however, infinity dock gives extra battery life. Adding the power of dock, infinity should have longer battery overall. Plus charging is much quicker on infinity than the iPad 3 (according to what I read, but it is true when compared to iPad 2).

So these hardware based features and I am sure other parts can be argued one way or the other. It all comes down to which ecosystem you like.

Personally, I chose (back) Android ecosystem. *Note: Some are hardware specific.

1. File System - I like to be able to organize files my own. I don't like iPad keeping same file copied at multiple locations for each applications.

2. Expandable Storage - I have many lecture video series with relatively large file sizes. I don't want to transfer/delete every time. Rather I like to carry around as a disk (in this case microSDs and quickly swap)

3. Applications - This may be perhaps what boils down to for everyone. For what I do, I like Android application selections.

For example,

A. Flash Card: I use Anki Flashcard application which is far the best flash card out there as it is cross platform; however, for iOS version they charge $20+; whereas, for Android it is FREE.

B. Ebook Reader: You mentioned GoodReader which is great PDF application on iOS but does not support Epub. Whereas, iBook has nice page flip realistic feeling Epub but their PDF support is terrible with no marking. So I had to use two applications to organize my ebook collections. Whereas, Android has Mantano reader.

C. Flash Support: It is true that Adobe is terminating the official support but Android currently plays it and unlikely to go away for a while. So until all the sites that I watch stream video becomes HTML5 compatible, I would rather have this feature.

4. True Multitasking - iOS's multitasking is very limited. It is highly controlled by Apple and for instance if you try to download a large file using browser, or other application, iOS terminates it quickly after you push the application into background.

5. Games - If this is what you are intending to use your table primarily, I say you should go with iPad. Selection on Android games are not as great as iPad and they lag in release.

6. Apple's Business Policy - They make great product that are not top notch spec-wise, but integrated so well and perhaps everything works in concordance and therefore bottleneck is not there; whereas, other devices have awesome and better spec but always have some bottle neck which hinders from other high spec components to hit its full capacity. But having said this, I don't like Apple's business policy with the way they keep suing, which to me seems to potentially hinder the advancement of technology. So yeah this is my personal opinion, but I am going for Android...

By the way, I do own MacBook Air, Iphone, and Ipad 2....

Now remember these points do not include jailbreak or rooting/custom firmware. Though I am sure they change the game quite bit but I am not familiar enough to make comment about these.
