Ok here's my dilema...I was thinking about getting the Xenerc 7" touchscreen..But a little confused about it... Now is the touchscreen only good if u have a car pc...would it work if u just get a regular dvd player??

I want the car pc, i mean who doesnt..But it's real confusing expecially if u dont already have a pc to use... And could get very expensive buying everything spererate...

The other route was to go with a Xenerc touchscreen and just a regular car dvd player, now still keeping my bose set up... Thats way i'll still be able to view movies and play cd's on it aswell...
what do you guys think?? If i can get a pc how much would a decent one cost?? Little tight on money right now saving up for down paymt on a house... any info would help, thanks...
