I have 2 Alpine HUs. 1 is a double din touch screen (IVA-W505) in my daily driver, and the other one is a X100M in the Crossfire. The thing I like about the Alpines, is that they were designed to be an iPod HU. The Clarion seems to include iPod functionality as an afterthought. I like the way the Alpine displays the iTunes album artwork on the display. Everyone has different needs and likes, but the Alpine HUs fit me well as my primary source for music (and movies/podcasts in the IVA-W505) is my 120GB iPod Classic or my 32GB iPod Touch.
