First off let me state that I'm not very familiar with laptops and PC Cards.
I have a Dell Inspiron 1000 and it doesn't have an integrated wifi card. I'm looking to buy either a USB Wireless Adapter or a PC Card. I never used either and assume that a PC Card will provide a longer range and I hear USB Adapters heat up a lot. My problem is with compatibility. My question is, do PC Cards universally fit into all laptops with a PC card slot? If not what should I look for?
