Query: Great concept. Poor execution. Poor support.

I bought my z540 in November 2004. It NEVER really workd: I had some problems with the DVD player, with the TV tuner, etc. HP Support has this great online chat feature but decisions are hard to get. They had me replace the DVD reader (they sent me wrong instructions, applying to another type of machines...), they then wanted ME to re-install the operating system. They were not happy when I mentioned I could not transform myself in an IT guru. I asked for a replacement or a refund. Got none of these. Had to ship the computer for repair, per HP under 6 to 9 business days. It's been a month now and HP Support just called me pushing the delivery date by 5 to 7 more business days (totaling about a month...).Conclusion: I don't know what you will do, but if I personally had to do it again, I would not re-do it... Not with HP... I love the concept of a PC being my radio, TV, CD, DVD, etc. all into one box... not with HP...
