I got a new Mac mini last week. This is an amazing computer. It's a 6.5 sq. in. 2 inch tall box packed with everything you would need in a computer at home. Intel Core Solo 1.5 GHz processor, 1 GB DDR RAM, 60 GB hard disk. The external interfaces include 4 USB 2.0 ports, 1 firewire, 1 DVI (with DVI->VGA adapter), analog and optical digital audio in/out, bluetooth, WiFi. It comes loaded with Mac OS X. It also comes with the remote.
Out of the box I was able to hook it up with my home theatre system without any problems.
I have connected my Samsung DLP TV through the VGA port. It supports 1280x720 resolution.
My wireless USB keyboard/mouse works just fine with this computer.
I was able to hook it up to my home wireless network with a few clicks. I was able to mount my Windows shares from the network without any trouble.
I have connected it to my home theatre receiver through the digital optical output. It supports 5.1 Dolby Digital sound when playing DVDs.
The best part I like about this computer is the 'Front Row' application. With remot I can play iTunes, play DVD or see slide shows or play a movie from my computer. The Front Row display is very nice and easy to operate. Since I don't have to pull up the keyboard just to listen to music I really like this interface. I was able to program my multi-device remote to control front row, so I don't even need the Mac remote anymore.
This is my first ever Mac computer. I'm still learning the finer details of using Mac OS X. But I find it easy to use. Having lived in Windows and Linux/UNIX world for all this time, it's not easy getting used to a new OS.
