A:AnswerSince this has a windows OS and has an alright processor, yes you can download and play games which don't require a large amount of system resources, like minecraft. Don't expect to be able to play Skyrim, Fallout, or Arma on this though.
Assuming you have an internet connection, yes you can video chat on this. using either Skype or other softwares will alow you to do this.
A:AnswerYes, Itunes for windows can be download and be used to sync with your iPhone. It will come with a 30 day trial of office 365, but you will need to purchase office either at pickup or shortly afterwards. If you are in school, always check if you can get free office, otherwise they normally do $20 off at purchase.
A:AnswerGood question. You can play certain games on this laptop. You won't be able to play graphics heavy and memory and processor demanding games on this laptop. I recommend you look at the system requirements on the games you want to play and choose a computer based on those requirements.
Since this laptop does not have a built-in backlit keyboard, you can use a lap desk with a built in light to light up the keyboard. There is nothing you can add to the laptop that will light up the keyboard from within the computer.
I hope this helps.
