Good place for your Macintosh repairs in the DFW area. The lady actually grabbed a power cable and checked to make sure it wasn't something simple before accepting my laptop for a diagnostic fee of only $45.00 with a promise to call this afternoon or tomorrow morning. CompUSA could have done less for more.
Oh, and they are authorized Apple specialists. The place is covered in Macintoshes and Macintosh posters, and my repair order statement is printed in the official Apple font and everything.
/me makes a note that I've fooled with CompUSA for the last time.
