Query: Pleased with the product, but

I used the Amazon information to go by, and one thing that I was specifically looking for was a serial port, as many of the applications I run require a serial port connection. I got the device and was very well pleased with it, however, it had no serial port! I like the device well enough to give it to my son, but I am disappointed with the product presentation by Amazon. If you have no need for a serial port, it is a lot of machine in a small package, and I liked it a lot other than the one area. I should have done more research on the device at other sources of info.
