Arduino Serial Connection Without Adapter

Hi, I'm an Arduino NOOB. I want to buy the Arduino Mini but it does not have a USB port. Would it be possible to use a Serial-to-USB adapter like this http://bit.ly/RpUAYL and connect it to the RX TX connections on the Arduino Mini? If not what Low-Cost adapters can i use and why cannot the RX TX thing cannot be done?

Would it be possible to use a Serial-to-USB adapter like this http://bit.ly/RpUAYL and connect it to the RX TX connections on the Arduino Mini?

No.

That thing produces RS232C level voltages which will fry the Arduino, as well as being inverted.

An FTDI cable will connect to the PC and to the Mini's TX, RX, and ground pins.

Thanks for the info!
