Same here. I have a 15" lenovo W530. It's not thin and it's not light, but it packs enough of a punch and has a large, hot swappable battery. I just wish it came in 17 inches and had a better trackpad.
I loved my Lenovo W700, which was 17 inches. I keep thinking i should actually replace the keyboard and battery and put it back into service as a secondary machine. It was fantastic, but they stopped making the W7xx line several years back. :(
