Your worrying about 10 pounds? Wow, you must be weak as hell. I'm not that big on IPS screens so I doubt I would notice a difference. For the lower resolution, I do agree, that was a setback when I saw it, and quite frankly the only thing I like about the Macbook Pro (Besides OS X).
Well, when you are like me and have to haul around a laptop every day, a binder of software, 3 external hard drives, a tool set, extra cables, power adapter and so forth, every pound counts. My back pack probably weighs 40lbs, and I carry it every day to work.
I think that mobility is key feature of a laptop, which is why I like mine slim and light weight.
IPS technology does make a huge difference in color saturation, which is why Mac screens look so pretty. It is also, super freaking expensive.
So, again, until you can show a PC laptop spec for spec that is cheaper than an Apple with all the same parts and features you cannot say they are over priced.
For the record, 10lbs for a laptop is absurd. That thing must be huge and clunky.
