Front row is just software that allows you to press a button on the remote and get your pictures up, or watch a DVD, or listen to music etc - it is not really anything special
Certain graphics cards have come with the facility and similar software for ages. My PC has a remote and similar software too, and also I can listen to the radio as it has a radio card built in which works with remote/software. It is 2 years old and never gets used - I tried it out once but it is more of a gimmick, and more directed at those who would find it easier to press a remote button to view their pictures than to control the actions with a mouse.
It is also designed so that people can operate the computers with the remote in the front room along with their TV. The PC I have has a scart built in (yes a scart, not phono sockets), and also has a TV antenna for freeview channels as well as the media software as previously mentioned.
The idea behind this is to connect it via scart to your front room TV/DVD, and watch freeview and record programs with time lapse if needed (I press pause, it carries on recording, so I can watch it from where I paused an hour later after the program has finished on the TV.)
You are then using your PC as a full media centre entertainment item. It looks like Apple are moving the same way. Mine never gets used and has not even been connected to the TV. To be honest, a lot of it is gimmicky. I much prefer a standalone DVD recorder to record off the TV, and I prefer to navigate to my own pictures and music files.
If I put a DVD in the computer to watch, it auto loads anyway, so no need for all the bloated software to allow me to press with remote to play it. Some people may find it useful, but, IMHO, you are much better staying with the machine you have because if you take front row and the remote out of the picture, there isn't a whole lot of difference
