Mine is a DV6663US, it was $1,000 when I bought it 5 and a half years ago.  It started having overheating problems probably the second year I had it.  Since then the hinges have broke, and it will randomly shut down from heat.  Now it won't go more than 5 minutes without shutting off.  I've had a couple friends with HP's from the same era, also had broken hinges and other issues.   
To those suggesting Asus - it seems like to get the same specs as other brands, I would have to spend about $150 more.  Does this sound right?  Conversely, Acers seem to be too cheap compared to everything else, that kinda scares me off.
