After our mixed feelings on the HP Envy 13, we were excited but also a little bit scared to see the 13's big brother, the Envy 15. It's running a Core i7 processor clocked at 1.6GHz, and has 1GB ATI Mobility Radeon HD 4830 discrete graphics fronted by a 1920 x 1080 15.6-inch display despite the fact that it doesn't have a built-in disc drive. Luckily there's an external Blu-ray packed into the box (that's a $225 option on top of the $1,800 base price), but most games and apps these days are available via download anyway, so it's not that big of knock on your power-user cred. The unboxing experience is actually identical to that of the Envy 13 (quite elegant),
