I would suggest a wireless card from anyone of the cell phone companies in your area. You might also be able to pick up wifi but it would just depend on your location.
yes if you have an internet service provider (comcast, AOL, Verizon etc.) or you are in a wi fi zone. You probably have to go through some sort of setup when you first try to connect to the internet.
Yes. A PSP-Go can access the internet via the internet browser. It also has Skype. However, don't expect it to be very fast ;) EDIT: Yes, he is right. Skype isn't very fast, they need to improve it....
If you have an ISP (Internet Service Provider), you have a good chance of going online right after receiving a laptop from an online seller. You may need to do some set-up with the help of your ISP....
