Laptops with no serial ports

I just bought a Dell Latitude E5510 laptop directly from Dell and it has a serial port. I found it rather strange for a brand new computer to have a serial port, so I Googled serial ports on laptops and this site popped up as one of the first. I believe it is one of their cheaper business computers. I'm sure I will never use the serial port, but I wanted to let you guys know in case you were still looking for one.
