Asus F50SV vs Sager 7682

I'm having trouble deciding between these two machines. The differences are:

1) 15.4 16:10 screen in either 1200x800 or 1680x1050 vs. 16.4" 16:9 w/ 1366x768 res only

2) Intel wifi card vs whatever Asus uses

3) eSATA port (I'm agnostic here since I will mostly be using a My Passport bus-powered drive)

4) Nvidia G105M vs GT120 (my only need here is something good enough to play BDs and HD video without too much stress so either should be plenty)

5) Weight -- 7682 ~5.8Lbs vs. ~6.3 for the Asus (is a half pound even worth worrying about?)

6) Price -- The Asus can be had for roughly $300 less given the same general specs (P8600, 4GB RAM, 320GB 7200 HD, BD drive), including 2-year warranty and 1-year ADP both direct from Asus.

The reason I'm conflicted is that I had a Sager 8790 and loved it (albeit after ATS took it in for warranty to replace the mobo after the overheating/artifacting deal), but Asus seems to make some top-notch stuff, and the price is definitely nice.

My use will be mostly for reading docs and PDFs, word processing, web browsing, email, and recreational video watching. I want something that is reasonably portable so I can fly with it and such, but I don't need anything too small, especially since my big hands need a big keyboard (hence why 15-16" is the sweet spot).

Sorry if this is confusing, but any help here is much appreciated!

Either resolution is fine from a usability standpoint (I can get used to scrolling a little more), but I just want to avoid having to squint to read everything on the 1680x1050 display. For instance, with my old Sager 8790, it was a 17" screen with 1680x1050 res and viewing from any distance (more than a foot or two) the text could be tough to read. I have seen mixed reviews of changing the DPI to make up for resolution --- is this a good solution to with higher res to get the best of both world or not?

That's a good thought. I'm just at the stage where I'm thinking "are the differences worth $300?"

My point exactly -- that even if I tack on an additional year to the Asus standard 2-year warranty, that would set me back about $150. Now if the Asus only came with a one year warranty, the $300 would be a good deal for the 3-year warranty (I also put in 2-year ADP in my PCTorque Sager config), higher res, and half pound less weight. However, since the Asus comes with a 2-year warranty and 1 year ADP already, that's where I'm thinking the cost savings with the Asus might be worth it.
