I really have no complaints with this notebook. I am on my second one as the first one I had, had a dvd tray that wouldn't close. The second one I got works perfectly.
It's very fast, video playback is smooth, sound quality is very good (as laptops go). Has plenty of memory to run a multitude of things in the background and then some. I haven't experienced any lag yet and I typically have multiple windows and programs running.
The aesthetics of the notebook are amazing I love the swirled aluminum affect, it gives it a really nice solid feel and a cool touch.
The keyboard is very nice, no wiggle in the keys that so many laptops have. Everything on the notebook feels very solid.
Battery life is far above average I would say I get a solid 8 hours with moderate use, mostly internet surfing with a 30 min show or 2.
Heat displacement hasn't been to bad my left leg gets a little warm sometimes but for the most part the notebook stays nice and cool.
Screen is very bright and has very good contrast.
The graphics are kind of weak if your expecting to play any major games off it. e.g. Battlefield, WoW, Homefront, etc...
Have not used the built in WiDi yet but I can't wait to try it; awesome option to have! WiMax works great on 4G. The WiFi range is good overall will pick up from quite a distance.
Overall I am very pleased with this notebook and would certainly recommend it to a friend. Previous reviews show some malfunction of hardware but sometimes bad things happen to good electronics. Don't let one or two bad reviews sway you from a really nice notebook.
