Compare Safari and Rover apps, noting similarities and differences as you find them. Which do you prefer?

First to compare the two applications, as I saw them they are not really comparable as much as they are compatible.  Is I saw in the videos the Rover program simply expanded the capabilities of the Safari App.  I will admit I was very impressed with the Safari App though.  The search function within the web page was very nice.  There have been a lot of times that I have been lead to a webpage by the promise of a quote or a reference to a subject, only to find it is a PDF with 100 pages and it took forever to find the reference.  I would have loved to have this search function.  

The Reader function was also very nice.  It would be very helpful to show on a projector screen in class and remove the advertisements.   The Reading List could be incredible useful in a classroom setting.  If there was a subject that you wanted your students to research, but as a teacher I wanted to limit the sites they could visit the Reading List would be very handy.  It would allow them the ability to view at their own pace, but they could not have access to the whole World Wide Web.   I could imagine the link through iCloud could have its uses, but I don't see this being as useful as the other benefits of the Safari App. 

The information about the Rover App was very useful in that Bandwidth is a major problem in our school.  (As a side note a couple of years ago at Maryville Christian School there were some teachers that were using either Rover and Puffin programs.  Every time they were on the School's system it would crash.  Our IT person blamed the Apple Computers for the crash and even though he could not prove it, the Apples were banned from the system.  The crashes stopped and the IT person felt justified.  I am wondering now if this video on the Rover would explain the crashes.)  Anyway in light of the video's it would seem that if our school used iPad's or any of the OS systems that use safari we would need to plan on not using the Rover application.  

The question would be whether it would be worth using the Safari's app or not.  There are a lot of great tools with the Safari, but I am afraid what we would be giving up by not having the flash player to view the animations would be too great of cost.  Now on the other hand as the IT people at our school are actively trying to widen the Bandwidth even as I type it might be worthwhile in the future.
