Question about Display and Cases

If you are talking about the third generation iPad no one here will know until it is released.

Yes

 

1. How is the display in sunlight/on a bright day? Are you able to read on it? Watch movies?
Not very good (at least with my iPad 2). You can just about see everything in the screen, it's usable but only just..

3. I'm going to be using this as my computer for the next 2 months. (Waiting for Ivy Bridge) Would I be missing out on anything not having a laptop?
Not that much, only if you do heavy video/photo editing, or graphic design type things. I use my iPad for about 90% of my computing and much prefer using it!

 

If by HD movies you mean 1080P, a few--with a file size between 3-4 GB each (you can check 1080P file sizes in iTunes now), 4 would not fit with any room remaining for apps, books, and other content ect...

 

You may want to invest in a bluetooth keyboard or one of the cases that has a keyboard built-in, if you're planning on using the iPad as your main computer for a couple months. Depending on what you intend to use it for, of course.

 

1. Can I use this without having to connect it to a computer at all? Also, can I use iTunes on a public computer to transfer music and videos to the iPad?
Yes, you can use & setup your iPad without a computer, and iCloud will also back your iPad up every night. I am not sure about using a public computer question though.
2. Supposing I use it for two months. Can I reformat it to the stock version to give it to my mom to use? Or what do I have to do?
Yes, you just go to settings, reset and select 'Erase all content and settings' and it will restore your iPad to factory settings.
What about multitasking? Can I use teamviewer and Skype at the same time?
Yes you can do that, I just tried it with an audio call and it all works in the background, I'm not sure if your camera will work in the background though.
