HP has put out some really stinky laptops in the past. But also plenty of good ones.
It's a good value for the whole package and should be no better / no worse than average for any similar type laptop in the same price range.
For comparison:
DELL XPS 17 (L702x) 17" Notebook should perform nearly identical with the HD dv7t
ASUS G73SW-XN2 17" Notebook a step up in gaming performance with the GTX 460M graphics
If you could find one of those in a no-tax free shipping option (like from Amazon) you might want to consider those.
Asus has the 2 year warranty and 1 yr accidental damage coverage as well.
