To get Skype on your PC/laptop all you need is a device with a web-cam and microphone (most new laptops have a web-cam + microphone built in) You will have to download Skype off the Internet for free for the basic package or you can pay if you need extras, but if you just want to chat live with mated the free one will be fine. When you download Skype it will probably ask you for a name, it is best to use your twitter name so that you can tweet the link to chat live.
You can use the PSP microphone to make phone calls using Skype.
Skype is a type of video conferencing software. You would install the software on your computer. To effectively use it however, you would need a webcam and microphone, which are hardware components.

Any microphone that works with your computer will work with skype. Logitech makes a lot of great microphones. You can find them at Best Buy or Walmart.
To have a video conference, you need a device with a camera and microphone, internet connection, and video conferencing software like Zoom or Skype.
Skype does not require you to have a webcam, or even a microphone. If you wish to make video calls, you do need a webcam, and to make calls you need a microphone, but you can just use the chat option if you want.
All you need to use skype is a mic and headphones. A USB headset with mic works best. Also some laptops have mics built into the and you can use that. You can't use a phone unless it's a skype phone, which you would know if you had one.
Internet, Microphone, and some speakers.
Be smarter than the microphone. You click on the microphone button at the top left corner and it should be on. But it depends if you are using a laptop or desktop computer. If you are using a desktop computer there is no microphone. But if using a laptop, click on the microphone button on the top left corner. Then the microphone should turn on.
Nope, you don't need to use a headset if you already have a mic.
