Hi again
Omercira - I'll take a 'first try' at addressing 'some' of your questions (using your numbers above):
1. Viewing the iPad is similar to a modern computer display - 2-3 hrs should not be a problem in my experience - what did you hear?
2. For standard use, the battery should last 8-10 hrs on a full charge, but depends on what you are doing & what you have 'turned on'?
3. Are you're asking if the iPad will have a 'problem' - certainly possible but uncommon - my iPad 2 after 2 yrs is fine.
4. I've never used a stylus - have a BT keyboard for extensive input - will have to let others respond.
Below to further expand on #2 above is a pic from my battery app - shows the time remaining on my current battery charge - gaming & browsing will consume more power; if your Wi-Fi and Bluetooth are on, then more power is consumed - there are other considerations, so there is NO exact response to your question, e.g. if you listen to just music for days, your iPad will continue to put out sound like the Energizer Bunny!
