can all be done within £450, you have touchscreen lcd(lilliput or xenarc), mini mac with airport and bluetooth about 1.4hz 60gigs, p1900 converter ac dc (http://linitx.com/product_info.php?products_id=728) and you are pretty much ready to go. Also bought (Griffin Powermate USB Controller) for volume increase and another amp)
You can listen to itunes or cds, radio, dvd's view photos watch mpeg clips, go on to the internet, play games, design photoshop (usual stuff you do on macs generally) have sat nav, work as a hands free kit for phone, reversing camera the works. Was gonna buy an alpine head unit but thi is far better and can chennel through my bose speakers and 15" sub.
So much better
